I originally used mercurial and its queues (mq) extension and then found StGit when switching to an organization using git for version control. Thus I got used to the patch-stack model prior to really being exposed to git's interactive rebase.

Some days I wonder if an interactive rebase oriented workflow would be good enough for me, but manipulating the patch-stack with StGit has become so second-nature that even the small amount of extra friction of `git rebase -i` sends me right back to StGit.
