I agree with some of the other commented that the sequences may not have a lot to satisfy you at the expert level.

Personally, I tend to favor the weakest form of panpsychism I can reasonably get away with. Probably I read too much Teilhard? I'm deeply impressed by the observation that Gödel's completeness theorem 'extracts semantics from syntax', the implications this has for semantic engines such as myself, and for the relationship between mathematical reality and material reality.

I suspect that most philosophy of mind you find on LW will be monist, but after that all bets are off.
