I'm really not an expert on revision control systems, but just off the
top of my head it seems like there are just too many of them, and
there's bound to be some kind of "market shakeout", leaving a "Big
Three". Right now, I'd guess that those three would be Subversion, Git
and one other. I really don't know whether CVS will survive -- there
are still quite a few projects using it, but I can't actually name
one. And I don't know if Mercurial, Darcs, and Bzr have enough
momentum to be worth thinking about.
My experiences with Git for my own small projects have been, shall we
say, less than satisfactory after about six months, compared with
about two years of Subversion and about ten years using ClearCase at
my day job. But that's just a learning curve issue, I think. Clearly
to be an open-source hacker, one *must* be Git-savvy, and all of my
new projects are going to Github.
One other question for the community, though -- is there room for
*another* version control system specific to the Ruby community,
tailored to our unique needs?

I've never met a happy clam. In fact, most of them were pretty steamed.
