In my experience Sugar has been much worst than both GNOME and mozilla
though. I know it's not easy but we should keep trying.

I had at least one obvious bug fix patch unreviewed for months. Maybe
I was unlucky. Anyway I agree this is the easiest of the cases and
where things work best.

While I agree with you in general, I think maybe we are exagerating a
bit the responsibility of the maintainers a bit. I tend to think it's
the whole community which will get the blame if things goes wrong...
Maintainers have of course a very important role, but they should not
feel like they alone into this.

I think narrowing the focus is the best we can do, but I'll elaborate
more about that while answering Gonzalo email.

Even if we go with my propiosal, I think maintainers should keep a
strong supervision role on features, UI or not. I'd say it's
responsibility of the reviewer to make sure the maintainer is happy in
this regard... we should add it to our review checklist (well we don't
have one yet afaik, but we should).

In an ideal world, a reviewer which is not busy with 0.98 should have
given a first pass to the patches and at the same time started a
discussion, involving the maintainer, about the oppurtunity of adding
such a feature etc.

There a couple of important differences compared to what we are doing:
* The reviewers are explicitly entrusted by the maintainers. So they
know if they review the patches will most likely go in. It's often not
very motivating to do reviews without being able to approve.
* The reviewers takes care of merging, so there is no blocking on the
maintainers (if not for an high level discussion on feature changes).

I thought about this a lot in the past and honestly I don't have a
good answer either. I think it's less urgent than adding people that
can do reviews. Hopefully we will figure it out at some point!
