When I first started playing with Python and Django, I was introduced to Mercurial. I had used Subversion for a while and once familiar with Mercurial, there was no going back (well...when I had the choice ;-) ). I've posted before that I use WebFaction as a host for my personal projects. This hosting also included setting up my own Hg server. I was happy, until Ken Cochrane turned me on to BitBucket.
