I think your going to need something else to drive attention/use of the site.<p>Right now it's basically a standalone GIST app with out any of the social networking bits.<p>If I were to rate the idea as-is I'd probably give it a 5/10 it seems like core functional works but there needs to be more...<p>How do you intend to monetize the site?
(premium services, ads, acquisition?)<p>Somethings I'd look into.<p>1. Add Group Feature (Private Group Bit Repository)
2. Maybe some kind of game mechanic to drive initial traffic and increase the sites stickiness. (pts for posting, badges, etc)
3. Plugins for Wordpress, BBS, Facebook, etc.
4. Try narrowing your niche "Business, Open Source" you can always expand it later.<p>Just some thoughts...<p>Good Luck<p>-N
