Last week Andy and I were at WDCNZ [1] and gave a talk [2] in front of a
crowd of 150-200 web developers. It was very well received (especially
the demo [3]) and both Andy and I fielded lots of questions after the
talk. It was also live-blogged [4] on the Xero blog.

One designer even said to his colleagues that they should use Persona
for all of their sites :)

# Accessibility

Someone asked whether JavaScript was required and that response lead to
an interesting Twitter "discussion" [5] with an accessibility expert.

I talked to him afterwards and he recommended Knowbility [6] as a good
organization to hire to do user testing on users with a variety of
disabilities or assistive technologies.

The other thing he pointed out is that if we manage to make Persona
Section 508 [7] compliant (which is basically a self-assessment based on
following the applicable guidelines), that could attract a number of
organizations in the US that are required to be 508 compliant and to
only use 508-compliant vendors in their user-facing products.

# Interested developers

I spoke to several folks were interested in trying it out for their
(proprietary) e-commerce sites. Many of those were looking at options
and were pleasantly surprised to see something so simple.

Andy also spoke to a few developers from SilverStripe afterwards who
seemed keen to add it to core (pending acceptance) so he'll follow-up
with them later. We both also spoke to a developer from Open
Polytechnic who could see great potential with using Persona internally.

# Questions from the audience

- Can we use it in mobile apps?

- Can we use BrowserID without the Mozilla branding?

- When will it be native in other browsers?

- What happens when users change their email address?

- How many people use Persona to log in every day? How many sites use it?

- What proportion of users pick Persona over Facebook when both are

- What happens when an identity provider goes down?
