Ask HN: How do you learn emacs?

I'm a Vim user, but I use Haskell a lot and it's not uncommon for me to find myself using clojure or scheme/racket. Vim is kind of the new hip thing so there are plenty of free resources online for learning it, and that's how I learned it about a year ago. Unfortunately, emacs seems to be less mainstream right now so there aren't as many resources, and what is available tends to be the very basics, that are found in emacs's built in tutorial.

In vim you usually don't learn about new setups by learning everything possible in the editor and coming up with a new way to use it, you take pieces from other people's setups and make your own. I assume it's similar in emacs which is an even more monolithic beast. Where can you go to find people sharing their setups?
