version control options

[Doug Hellmann]

I'm researching hosted VCS options to move the PyMOTW sources off of
my private svn server to a server that will make collaboration
simpler. I've identified a few alternatives:

1. Google Code (svn)
2. Bitbucket (mercurial)
3. Launchpad (bazaar)
4. GitHub (git)

I'm not all that keen on git, mostly because my impression is that it
is hard to use. I have no direct experience, so obviously that has to
be taken with at least a grain of salt.

I'm familiar with svn, have a good tool chain built around it, and use
it on my other projects, including Google Code. I don't have a good
sense for the barrier to entry for other users, though.

The two other DVCS options seem to have mostly similar feature sets,
although I'm still reading about them so maybe I haven't hit the
differentiating features, yet. I know that the Sphinx project uses
Bitbucket and I've been told the Python core developers may be looking
at bzr (but probably not Launchpad).

I'd like to hear your opinions about the above options. I know these
sorts of discussions can turn heated, so please keep it objective. :-)

Thanks,
Doug
