Mercurial is common enough (used by Mozilla and similar projects) to be an interesting VCS for projects which could need contributors (I have others on Darcs and SVN), it has a good, mature and very alive ecosystem (unlike Bazaar), it has a lot of useful plug-ins (e.g. for history rewriting) and not a totally broken branching/merging mechanism (like Git).
Edit: at least I have managed to fsck up a Git repository twice while merging two incompatible branches. Never happened with Mercurial.

Ahh I see.
