I browsed the ISADIY2010 site quickly and also have to agree that it’s great. Excellent, even. Fun, easy to use, graphically relevant. A pleasure to use. I don’t think I’ll get a chance for further review, but it seems like you have it above par on the whole so I don’t see the need to get into details and nitpick. Great work.
Can you maybe hack the IDSA site to make it as good 
? (even half as good would be an improvement).
I’m watching from afar (up here in Canada) but the quality of the site alone makes me wish I could attend. I’d say that is a ringing endorsement!
