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.

You're right - my argument is intended for easily reachable improvements.
Your brain is full of neurons that are sending chemical messages to one another. For this to work, the brain has to be able to receive all the messages sent, and to send all the messages received. Your extra chemicals have to change this process somehow, and they can only do this by interfering with the signalling process. But your body already knows how to make these signals.
You're not creating hard-to-reach improvements by adding chemicals. You can only alter the balance of the chemical network that already exists, and evolution has already balanced that network pretty well.
If you could do something more radical, like adding a different kind of signalling, or fundamentally speeding the thing up, then I'd be interested. But chemicals can do neither of those things.
I think you're assuming that all brains are in pretty good shape, but there are people who benefit tremendously from psych drugs.
It doesn't seem implausible that there are people who'd benefit from less drastic tweakage.
