Another problem might be the start page, at least I think the entries there are too large, so you don't see a lot of them at once. I'd show just the first line from the description on the start page, that'd make it more compact. And put the 'Recent projects' bar to the left, it's a bit lost on the right side.

I agree with this. The start page entries are really too large, not helped by the extremely accessible font size used on the site.
I think perhaps the index needs on there to give software categories on the first page, that would be very useful.
Also a one-line "about" or "mission statement" piece of text somewhere at the top of the page wouldn't go amiss. To the new and uninitiated user, the whole concept of the site may be lost.
