And I'd like to know about separate quality place to discuss self-help/improvement, as the original poster suggests.
ISTM that instrumental rationality overlaps a great deal with self-help/improvement. We could avoid the latter only by restricting ourselves to discussing epistemic rationality.
I don't want the more practical or self-improvement posts to overwhelm the more academic or posts, but I don't think the balance is too far off yet.
Here's our place to discuss Less Wrong topics that have not appeared in recent posts. Have fun building smaller brains inside of your brains (or not, as you please).
