But i've seen a few recommendations of his writing here. Maybe i should reconsider my judgment of him. I know you linked to a debate with him and Robin Hanson... but that's a 72 minute long video.

I wouldn't recommend that debate, it's not exactly Moldbug's most shining moment.

A decent jumping-off point may be his formalist manifesto. There are probably some other good starting points (Maybe this, this, or this )

Mencius tends to be very long-winded, but is a decent enough writer. Some of his sarcastic contrarian trolling can get a bit tiring, and he does repeat himself in different posts, but he at least has some unusual non-stupid ideas, I just wish he organized them better and dropped the sarcasm.
