how do I sell git to my colleagues?
stuff4ben: Is svn working for them?  What problems are they having with svn that git would solve for them?  If there isn't a compelling reason, you're probably better off sticking with svn.  OTOH you could use git personally as a front-end to svn.  If your coworkers see an improvement in your development workflow then it might get them to switch.  And if I were you, I'd let them know how much easier and faster development is for you on git.
