It looks similar to svn in the commands it use ; also, I know it's used by Google Code project hosting, which I use for other projects. If it works well for Haiku, I know I can switch them to use it too.Also I would be curious why so many people prefer Mercurial. My vote is pretty much just laziness: I know Git. From what I've seen Mercurial is pretty similar so I'm not going to be too upset if it wins the vote. But I'm curious if the votes are more like mine (people just already know Mercurial) or if there was a definite preference for Mercurial after using both. If the latter, why?
