Welcome to the class
Web 2.0 includes web-based communities and hosted services that enable you to learn from, collaborate with, and socialize with others. From blogs to web-based applications, web 2.0 is becoming a valuable tool for all industries and sectors. In this class, you'll discover how web 2.0 facilitates collaboration and communication, and you'll learn how to safely and securely use the tools and services offered by this next generation of computing.
This class is designed for computer users in the education and government sectors who want to learn more about the collaborative opportunities provided by web 2.0 tools.
What you'll learn
This four-lesson class focuses on web 2.0 concepts and technologies. Each lesson is accompanied by a short assignment and quiz, which are designed to reinforce important topics covered in each lesson. The following are brief summaries of each lesson:
- Lesson 1 explains what web 2.0 is, what it isn't, and how it can make your professional world more productive.
- Lesson 2 shows you how traditional office programs can be replaced with web-based alternatives so you can work anywhere using an internet connection.
- Lesson 3 explores how you can set up a wiki collaborative site that others can easily access and add information to. It also examines the use of social networking sites in the government and education sectors.
- Lesson 4 takes a look at blogs and RSS (Really Simple Syndication) feeds to help you drive communication within your organization.
Beyond the lessons, be sure to complete the assignments and quizzes.
Let's get started with the topics in Lesson 1.
The origins of Web 2.0
When you think about the internet, or the web, you probably think about surfing to websites that interest you. Maybe you like to read the news online or get information about a hobby. Whatever you do online, you probably don't consider it a place to conduct all your work or somewhere that you can interact as part of a worldwide community.
That's probably because we have a tendency to see our computers as the "real" place to get work done, and the web as a place to have fun. However, what if you could use any computer anywhere as a launch pad to completing your work, communicating with others, and offering your input on a variety of topics?
What if your word processing application, spreadsheets, presentation software, and anything else you used in your line of work were available on the web so you could access them from home, work, and the coffee shop? And what if, just by using these kinds of services, you were an integral part of a global brain?
Through a concept called web 2.0, we may find ourselves performing more and more job-related tasks online in the near future. Web 2.0 is basically changing the internet from a vast collection of websites to a full-fledged computing platform that offers any application you need and the ability to collaborate in real time -- online, 24 hours a day.
Web 2.0 service providers are well on their way to eventually replacing traditional desktop computing applications.
The term web 2.0 arose out of a brainstorming session between a book publisher and a marketing firm as they tried to identify the major turning point that was occurring for the internet in the early 2000s. During the dot-com collapse, web 2.0 began to take hold as more than a concept. The publisher and the marketing firm recognized that, although the early concepts of using the web as a business tool were still valid in many ways, a newer, more powerful concept of using the web as an interactive business platform was gaining ground.
In an attempt to benchmark and identify a set of new, innovative companies that were potentially ripe for investment, they defined those early days of the internet as web 1.0, and called the new theory web 2.0. To clarify what they meant by web 2.0, they came up with a long list of comparisons between web 1.0 and web 2.0 companies, as shown in Table 1-1.

DoubleClick, a web advertising company that businesses used to promote products and services. Ads were developed by companies and placed online in strategic spots similar to TV advertising. |
Google AdSense, a web advertising company anyone can use to increase income on a website. Ads are instantly generated and constantly changing according to website content. |
|
Britannica Online, an online version of the original encyclopedia. Written and edited by specific people. |
Wikipedia, an online encyclopedia written and edited by anyone. |
|
Personal websites. |
Blogging. |
|
Page views, where ad rates are determined by how many times a web page is viewed. |
Cost per click, where ad rates are determined by how often an ad is clicked by a user who wants more information or makes a purchase. |
|
Publishing, where a single person or entity controls and edits information. |
Participation, where groups of people control or edit information. |
Table 1-1: A comparison of web 1.0 and web 2.0 company characteristics.
The list goes on, but the general idea is that web 2.0 uses the internet as a computing platform to encourage participation and interaction; web 1.0 does not. Now that you have a general idea of how web 2.0 came to be, let's take a look at what's really involved in it.
What's involved in Web 2.0?
Behind web 2.0 is the idea that users can add value to the internet by harnessing their collective intelligence. As users add new content and websites, that information becomes linked with other users' content and websites. The connections -- or web of connections, really -- grows as a collective activity of all web users.
Think of eBay, for example. This company provides the platform for marketing and sales activities; the users make eBay the powerhouse online selling tool it has become. The more people use it, the more powerful it becomes.
Web 2.0 companies know that not every person can take the time to add content to the internet, so they build systems that improve just by having people use them. Amazon, for example, has a system that analyzes what people look for and buy. As a result, just because people come to the site and use it, Amazon can sell more products by leading with a "most popular" product that changes rapidly depending upon user needs.
In many ways, web 2.0 is about using the web as a global brain to make life easier for all of us. So, if that global brain is out there for all of us to use, why not use that brain to work more effectively and efficiently?
Wikis, for instance, can be created and then easily updated by others within your organization as policies change or as assignments are worked on. You can network with others to advance your career or goals without dropping everything to go to a meeting at an inconvenient time. You can establish blogs that enable two-way communication, allowing questions to be asked and answered at all hours of the day and users instantly notified of updates.
You'll learn about the collaborative aspects of wikis in detail in Lesson 3.
Keep in mind this concept of web 2.0 as a global brain; it'll help you see clearly how web 2.0 can impact your organization as you move into the next section.
How Web 2.0 can impact your organization
It's important to understand the difference between applications and platforms when you examine web 2.0 and think about how it can impact your organization. An application is a piece of software that lets you create and manipulate things. For example, a word processing program, such as Microsoft Office Word, is an application that lets you write or edit documents.
A platform, on the other hand, is the required framework that enables the application to work. So, to use Word for Windows, you need to have the Microsoft Windows operating system running on the right hardware (a computer with adequate disk space and memory). The combination of operating system and hardware becomes the platform that enables Word to function properly.
With web 2.0, the internet becomes the platform that everything else runs on. The operating system and hardware required for an application to run are located somewhere on the internet. It doesn't matter which kind of hardware or operating system your computer uses; you access the web 2.0 tools through your internet connection.
Using web 2.0 as a professional communication tool
Now, let's cover some specific examples of how web 2.0 can be used as a professional communication tool. In the education sector, educators are discovering the use of web 2.0 communication tools for developing a personal learning environment for themselves as well as a more public learning environment for students.
For example, you can use blogs to quickly provide feedback to students or post important information about a class. You can also create a wiki that shows your own strides in professional development to your administration, share an instructional video on YouTube, or use an educational social networking website to learn about new concepts in education.
In the government sector, purpose-focused blogs and podcasts can improve constituent relations without opening the door to issues you don't want to address. They enable you to target niche audiences to create conversations that increase trust. You can create a wiki to help shape public opinion on a certain topic, too.
Government organizations can use the pervasiveness of social networks to improve public safety, prepare and respond to disasters, encourage economic development, and deliver better, timelier services to citizens. Many scientists already use web 2.0 tools to share and disseminate public health information, such as H5N1 avian flu virus tracking project performed by scientists at Nature using the Google Earth mapping tool.
The communication possibilities with web 2.0 are practically endless. Any organization can use online calendars to ensure anyone who needs to know about events can easily access the information, for example. There are even online to-do lists that groups of people can follow, and RSS feeds can help push content to specific audiences.
The impact of web 2.0 trends
In the education and government sectors, students and constituents have a wide range of expectations about information sharing and collaboration. Primarily, they expect to know everything as soon as possible. Then, they want to be a part of what's going on even if their participation is virtual rather than physical.
The impact of web 2.0 trends, then, is substantial in creating environments in which students and constituents can be an integral part of what's happening in their worlds. At the same time, the environment can be a bit daunting because of the decentralized, distributed, and participatory process. In the past, these audiences were talked to -- not talked with. However, web 2.0 turns that idea upside down by requiring and encouraging participants to share information and collaborate with one another.
As you begin to use web 2.0 in your organization, it's a good idea to set clear expectations about what's expected of users and what users can expect from the tools you're using or provide. Two of the expectations that should be clarified are privacy and security, which are discussed in the next section.

Two of the expectations that should be clarified are privacy and security, which are discussed in the next section.
Understanding Web 2.0 privacy and security
When you work and share information online, you need to be highly conscious of the information that's being posted. In many cases, you're assured of privacy through the use of logon IDs and passwords; however, in some cases, you might not be.
For example, when you write a blog, it's typically done in a public domain that anyone can access. Posting student names and images on a public blog is often not a wise idea and may be prohibited in your organization. On the other hand, wikis -- which are also typically public items -- can be made private.
When privacy is a concern, you can use acronyms or screen names to protect personal names and information. If photos of minors are involved, you should obtain written permission from parents or guardians before posting them.
Any written permissions should specify that items will be posted on the web.
A major issue for web 2.0 in the U.S. federal government is 508 compliance. Because many web 2.0 tools rely heavily on JavaScript, web 2.0 projects must address 508 compliance issues prior to implementation. For example, a web 2.0 site must properly notify screen readers of changes. In addition, government webmasters must carefully consider how to properly collect information and have it reviewed, and state how personal information, such as Social Security numbers, phone numbers, and so on, will be protected.
The OnGuard Online website is a collaboration of several federal government agencies and technology industry partners whose goals are to help everyone remain safe and protected online.
When you use web-based applications, most of the websites that provide the tools also provide good security; however, you should check the level of security before you decide to use a particular service provider. Also, be certain that any web-based application provider has a backup system to keep your documents protected and accessible in the event of a disaster. If a provider has a backup system in the heart of hurricane, tornado, or earthquake country, ask about the building where the backup systems are stored. Most of the time, the buildings are designed to withstand natural disasters.
