Each of the tips is an important and non-obvious point, and several are unusual and probably good advice: post a cheat sheet, write down interesting commands, update your cheat sheet. Tips for beginners are always pretty generic. I'm sure someone, somewhere has suggested the same thing, but I give him credit for 33% unpredictable content, which is actually pretty good. As a longtime emacs user, I'm still working on a few of these. I often discover useful new commands and forget them by the time I need them again -- obviously I should have them posted on my cheat sheet. I don't use command-apropos or the included documentation as much or as well as I should, either. I think insufficient use of help is way too common -- a lot of people ask me for help as soon as Google fails them.
