If you're doing any rich interface development and/or Ajax work, you should definitely participate in the recently-announced Ajax survey created by Richard Monson-Haefel of the Burton Group. It's a simple, 3 question survey, and should only take a minute of your time.
Note that Spry is *NOT* included in the list of frameworks (heresy!), but I strongly recommend putting it in as a write-in vote if you're down with the Spry framework. Perhaps even if you aren't. ;-)
Update: Spry was added the morning after this post- nice! Let's hope it got prominent enough to rank, as the survey was going for a while before that was caught. :)
