coming from git, understanding mercurial branching

I've got a pretty good grasp on git's rather straightforward branching, but am trying to wrap my head around Mercurial's branching. There seem to be several flavors, some default to push-public, while others are private; some are tracked in history, while others seem more ephemeral; often the docs suggest cloning instead of branching; detached heads seem more normal in the Mercurial world.

Do any git users here have good "understanding Mercurial branches for the git user" resources they've found helpful when working with Mercurial? Preferably a "for dummies" resource with illustrations & comparison charts so I can see the big picture.

Thanks

PS: I've read a couple Mercurial resources including
http://mercurial.selenic.com/wiki/GitConcepts
but it didn't really dig into comparing the mental models used in
branching.
