Gerrit was created by and for Android: https://android-review.googlesource.=
com
It's used for Gerrit itself https://gerrit-review.googlesource.com
(dogfooding), Chromium and GWT, on Google infra.
It's also used by many companies contributing to Android (Sony, etc.),
and by Eclipse, Typo3, KDE, LibreOffice, Qt, OpenStack, etc.

Rietveld is hard to install outside AppEngine, that's probably why. I
would have loved to use it at work otherwise, instead of that crappy
ReviewBoard; we've fortunately moved to Git and Gerrit since then.

That said, Gerrit 1.x was started as a fork of Rietveld, but Gerrit
2.x has been rewritten from scratch in Java and GWT, built on top of
JGit.

WAT? You can't wrap your head around a DAG of commits and you want us
other mere mortals to use a tool you're building on top of a DAG of
transitive dependencies? (intentionally provocative tone to motivate
you to reconsider your position about git). Git is easy to work with
when you think in terms of the DAG in your repo; no need to be a git
black belt for that.
I merely use 5 git commands on a daily basis (using "git gui" to do my
commits and deal with my working directory; pull, push, checkout and
"rebase -i"; merges are generally done by Gerrit, at the push of a
button; on a relatively big project like GWT, I tend to use gitk, "git
log --grep", "git grep" and "git blame" quite a lot too; and this only
works well if you have a "clean history", which you cannot have with a
"commit then review" approach =E2=80=93 on master/trunk I mean =E2=80=93 bu=
t of
course, because SVN doesn't give you tools to easily look back at your
commit history, you tend to not care that much about having a "clean
history"; "git svn" mitigates it a bit).
