Because this:
The <script> link to the source is so hard to find.
I cant find this in the documentation (I am not saying it isn't there).
And not finding it there, I look into the example timelines, but their location of the JavaScript is ambiguous as they all link to it using relative paths, like this:
So this isn't helpful.
So, now I am thinking, lets look at timelines "in the wild" to get the link. And guess what, the site you look at has downloaded the timeline JavaScript and installed it on their own server. So that's not going to work.
In my opinion the location of the file, the name of the file and the parameter passed to the file should be easy to find. Really easy to find.
This is so bad that I was using the wrong server and thus the wrong source-code for timeline for A FULL YEAR!
The single most important piece of information that you need to use timeline is the hardest piece of information to find.
I wonder how many people wanted to use timelines and gave up because they couldn't figure this out.
This is not good news for our team.
