At the time, and in the weeks that followed, I was too busy to start comparing the sites. But this week I want to start pushing my code out to these sites to see how they work.
In terms of feature list, Github received a lot of love in the past weeks, as you can read from their new blog. But Gitorious is not standing still either. Both are working to provide an easier collaboration feature around git pull which is very cool.
update: arrgh, I'm a moron. I forgot to add my Github password to my Keychain, so I'm locked out of my account. There is no "recover password" functionality on Github yet (its on the Feature Requests page though) so I sent an email to their support account, and I'm hoping for the best.
update 2: Ok, access to Github restored, big thanks to Tom Werner. My profile page is at http://github.com/melo/. I have 5 invites now, so if you want one, send me an email or ping me via XMPP/Jabber. My address for both is
melo @ simplicidade.org.
