A place to discuss potentially promising methods of intelligence amplification in the broad sense of general methods, tools, diets, regimens, or substances that boost cognition (memory, creativity, focus, etc.): anything from SuperMemo to Piracetam to regular exercise to eating lots of animal fat to binaural beats, whether it works or not. Where's the highest expected value? What's easiest to make part of your daily routine? Hopefully discussion here will lead to concise top level posts describing what works for a more self-improvement-savvy Less Wrong.
Lists of potential interventions are great, but even better would be a thorough analysis of a single intervention: costs, benefits, ease, et cetera. This way the comment threads will be more structured and organized. Less Wrong is pretty confused about IA, so even if you're not an expert, a quick analysis or link to a metastudy about e.g. exercise could be very helpful.

I've never been able to get over the initial learning curve of emacs or vi.... every once in awhile I try for a few days, but find myself not advancing up the curve fast enough to get real work done and end up ditching it for a conventional editor. Do you have any tips for how to quickly bring yourself up to speed on one of the editors, i.e. get far enough up the learning curve to be more productive with it than with a traditional editor, in a short period of time?
Others have given good advice; in particular, the idea of using a cheat sheet. People have made nice ones, but it's easy to make your own. It should show how to do the things you're already doing in your current editor. Other than that, the "trick" is just to commit yourself to using your chosen new editor all the time (except for emergencies).
If you don't already touch-type, learn that first. You should have a diagram of the keyboard (or at least the hard-to-remember parts). When you forget where a key is, look at the diagram not the keyboard.
If you choose Vim, feel free to PM me if you can't figure out how to do something in it.
