Mercurial popularity is stagnant

[Peter Hull]

I'd say that hg and git are different enough to make using both
awkward, but not different enough to give one a compelling technical
advantage.

Unfortunately, as we stand, git is more popular (in free software at
least) so the rest is just momentum.

For example Mozilla use hg for Firefox but recent projects like Rust
have used git/github. I assume this is to garner greater visibility -
I would be interested to hear from anyone at Mozilla on this.

I can't see there being a 'solution' to this, but mercurial is and
will continue to be a strong solution for DVCS as long as the team
keep working on it!
