How do you guys use Mercurial

That website is a great read. It is what got me over the hump when switching from subversion.
My work flow is fork(clone) at the revision you need the bug fix for. Fix your code and then pull the fix back into your repo. This is where tagging for versions is a lot better than compared to subversion. If you take a look at tortoise HG with the codeigniter repo, you can see this happening.
I think all of your forward moving versions be kept in the default trunk, and clone/merge in bug fixes. This will allow you to roll back to any revision.
I switched about 3 months ago and it felt really strange at first because of not needing a central server. Bitbucket is kind of like that. You can pull changes from anyone and commit all the time. Handy if you need to back up a little bit and not mess up what you may have committed to the server.
