How can we ensure Bazaar (bzr) remains active?

These are all valid points. :-(
There's not enough incentive to use a system which is not popular, not
well supported, and appears to have no future. And, it's own users don't
appear to have much faith in it.
Like it or not, I'll have to use Git more; however, this will be
combined with using Hg also.
