I hate that description. I keep meaning to overhaul the project
landing page with screenshots and try to describe the feature set
better, but I've been too busy with coding.

We have a number of UIs for Git... some more user friendly to
certain classes of users than others. But I'm not sold that a
web based interface is the future.

Sometimes a web UI can be very convient to work with. Sometimes, the
existing mailing list review infrastructure works very well. What I
love most about Git is how much choice we really have as users.

Maybe. But I'm not actively pursuing that right now. If someone
else develops a Gitty bot for Wave, that would be cool.

Actually... my goal over the next couple of months here is to
make Gerrit Code Review no longer dependent on a web UI, or on a
backend SQL database. I'm going to shift all of the data storage
into Git meta branches, and the code annotations into Git notes.
Which will make it very friendly to build other tools like an Emacs
plugin that can interoperate based solely on raw Git commands and
formats, without ever touching the existing Java or web UI.

I think the biggest challenge I have is I need a good inverted
search index, and Git has no standard for that. I'm tempted to
use Apache Lucene[1] because in Java its simple to work with,
but their C port has been dangling in the wind for a long time.
