I think the category list should be updated and a few apps shuffled.
SpeedCrunch seems more Education- than Office-related.
The Internet category is a bit catch-all. I don't think Nvu/KompoZer need to be in the Internet category (development is just fine). Thunderbird doesn't need to be there either. It can stay in the office category or perhaps be grouped with Pidgin and Miranda into a new Messaging category (along with the Lightning Thunderbird extension).
The Utilities category has the same problem. Consider putting InfraRecorder into Music & Video (and consider renaming that category Multimedia). Consider creating a Security category for ClamWin, Eraser, KeePass, winMd5Sum and perhaps PuTTY and WinSCP. GPG would go there too, I suppose.
I am interested in what people think. This is such an awesome time for this site. I can see that the application count is going to explode!
