Why Bazaar is not used in many project hosting sites?

There is a degree of assortative mating here, where people or projects
related to Fedora are going to tend to choose Fedorahosted, and those
associated with Ubuntu or MySQL etc Launchpad and Bazaar.

Launchpad hosts 7384 projects in Bazaar <https://code.launchpad.net/>
with some 30,000 branches.  (There is a long tail of small or inactive
projects.)  We can't compare the percentages because bzr's the only
option for hosting on Launchpad, though you can get some data from the
fact that there are 1000 branches mirrored from cvs and svn.  (git
imports will be coming soon based on bzr-git.)

I believe Savannah does now support bzr, for at least some features.
