> I'm fascinated by your use case because for my professional work I've never created or shared a patch.

I do driver development, and often times we're debugging an issue where toggling some hardware (or software) "mode" can make an issue go away or appear. These are the patches we end up making and sharing with coworkers but never merging. We need to be able to do quick and dirty hacks but we can't be putting that kind of stuff anywhere near master branch. I'd say 4 out of 5 patches I write never get merged (and they're usually really short patches, the code itself wasn't of any measurable effort).

Moving from SVN to Git (or darcs/hg in my case) was certainly a big move. But I guess if you were coming from diff/patch/email/shell script background (like kernel before bitkeeper), it was probably very intuitive :)
