This looks good. How does the startuphook differ from running code in
main? It's easier for extensions to register hooks?

Well, the main reason is that this way, the startupHook can be run in the X monad, AFTER xmonad has initialized all its state and so forth.  Running code in main would only be able to run in IO.
