It's taken more than 2 hours to get my results - I'd love to get an email saying "After looking at your data, it looks like it's going to take N more hours to finish the results".
Yeah, that would be good. The main bottleneck is in sucking all the data down from Google's API - for a site with as much traffic as justin.tv, that can indeed take hours. Once that's done the processing itself is relatively quick. But that's certainly something we could notice and let you know about. (Consider this your notification for now...)
