Great discussion! I would like to share my perspective a someone who is
a (relatively speaking) new Git contributor and who has never interacted
on mailing lists before Git:

1.) "git format-patch" and "git send-email" work great for me. It took some
    time to learn how they work but now I have my own "submit.sh" based
    on those tools and posting a new series is a piece of cake.

2.) Initially it was hard for me to ensure that my patches don't break build or 
    tests on Linux and OS X. Travis CI helps me a lot. I just wished we could
    get Windows support, too.

3.) I noticed that I get two types of reviews. The first kind points out things
    in my patch that are obviously wrong. The second kind are things that require
    a discussion. When I get feedback of the first kind, then I am always super
    eager to send out a new roll just because I don't want any other reviewer
    to waste time on obviously wrong patches. However, I have the impression
    that frequent re-rolls are frowned upon. If we would use Git for the patches
    instead of email, then I could add "squash" patches to indicate changes in
    the current roll that will be squashed in the next roll (I know I could
    send squash patches as email, too... but for me that gets confusing quickly).

4.) Reviewing patches is super hard for me because my email client does not
    support patch color highlighting and I can't easily expand context or look at
    the history of code touched by the patch (e.g via git blame). I tried to setup
    Alpine but I wasn't happy with the interface either. I like patches with a GitHub
    URL for review but then I need to find the right line in the original email to
    write a comment.

Again, this is just my point of view as a "newbie" and I definitively don't expect
the Git community to change their established workflows.

Cheers,
Lars--
