dive into mark may be the best guide out there to accessibility, but I wouldn’t know since when I got there I had no idea where I was, what was going on or where to start. Like Bloggus Caesari coming late to the party means it’s almost impossible to catch up (no matter how many jell-o shots you do).
As these sites gain popularity and fame as their body of content grows and word spreads, it becomes more and more important for them to take into account new visitors who will need to catch up.
A “start here” button is all it would take.
