Having the project logo on a projects site would be nice.
+1 (but the logo should IMHO be hosted on Ohloh to not steal bandwidth and avoid problems when project page is unavaliable for some reason).
I also agree. And once we have image hosting built in to our system, perhaps we might also free ourselves from Gravatar, which a lot of users have had trouble with. No promises on timing, but this seems like a simple thing for us to do.
also free ourselves from Gravatar
I would probably wait for that step a bit. As Gravatar was recently bought by Automattic, it's service might improve over the next couple of months. :)
