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.

For something slightly different, I am attempting to increase my reading speed ( I am primarily an English speaker, but English was my second language, which probably explains the initial slowness) using QuickReader app for iPad.
This app lets you predefine the reading speed (timing yourself and word counting is annoying) and uses a pointer to pace you through the material.
I am up to 380 wpm in the app, cannot confirm how transferable the skill is outside of the app quantitatively, but it feels like there is some improvement, though sometimes it feels like I am rushing through faster than I comprehend; OTOH my iPad is always with me and I have electronic versions of a lot of my reading.
One thing to fix down the line is to have "trained modes" for materials of different difficulty and ability to trade off recall for speed.
