Why Bazaar is not used in many project hosting sites?

[Canol Gokel]

Hello,

My question is that why most of the big project hosting sites does not support
Bazaar while they support Git and Mercurial? The ones I'm aware of are Savannah,
Google Code and ActiveState... Also there are project hosting sites which
provides only Git or Mercurial source control. While the only project hosting
sites I'm aware of which provide Bazaar support is Launchpad and SourceForge.

I actually asked this question in #bzr a few weeks ago but didn't get a
satisfying answer. After reading that ActiveState will also support Git and
Mercurial but not Bazaar, a few minutes ago, I thought I should ask it again.

Is supporting Bazaar hard for technical reasons? Or it is just not well
advertised or something? I'm using Bazaar for a few months and I'm very
satisfied with it so far but the idea that I'm stuck with Launchpad and
SourceForge both of which I don't quite like as much as Bazaar, makes me
thinking of learning Mercurial or Git while I haven't gone too far with Bazaar.
