When and how to to contact the Git developers (gist)

At the Dev Summit, I mentioned this gist I've got lined up for whenever someone should consider sending an email to this list:

https://gist.github.com/tfnico/4441562

It's a handy link to share in some encounters, exemplified by Konstantin here:

https://groups.google.com/d/msg/git-users/Md72iVvPHqw/Zi3yFIRrR2AJ

I see that Peff already improved the git-scm.com/community late last year to cover some of the same points, but it is weighed a bit differently. Perhaps someone here would prefer to use my gist when redirecting people with "user questions" away from this list, or inspire them to write better bug reports.
