Switch, synch, publish, unpublish - those all made sense, but when they started adding things like 'sprout' and 'graft' it just passed into the realm of trying to be too cute with the branching metaphor for my tastes.
Personally, I'd pick git-flow over this. It seems more useful and makes, syntactically, more sense (though it can get a bit verbose at times `git flow feature start some-feature`). Starting and finishing features, hotfixes, releases, etc. handles all of the necessary branching, merging, and checkouts for you while adding structure and basically documenting the lifecycle of the code in your commit logs.
Maybe it's not as 'human friendly' as sprouting a branch, but starting and then finishing a feature sounds pretty straightforward.
