If I interpret "riff" as "rip off", I have to disagree here.
Citing a presentation of the original author of Mercurial:

Mercurial comes close in some aspects and is faster in others. In
fact git is much slower and consumes huge amounts of disk space if
you don't regularly do git-pack-objects. Which Mercurial such
cleanup work isn't needed.
And the blog says that the repository format of git is much more
stable, because it saves one file for each object while Mercurial
appends to file logs and truncates to the last file log size when a
commit or pull gets interrupted. But he doesn't mention that when
you start packing objects you'll move around all your history and in
case of trouble you'll have trouble with exactly this history.
I'm not saying that git will kill your data, but I'm saying that I
consider this at least as dangerous to your data as a simple
truncate (which only is done while a write lock is held).
