What features make it a worthwhile read, compared all the other clueless/useless philosophy (of mind)?
Almond (like Yudkowsky and (so I hear) Drescher), looks at these topics through much more of an AI/CS lens than most who write about them. There's also stuff in there of interest from the futurist/transhumanist perspective that's common on LW. I'll admit that many of the essays are long, and I won't say you'll want to read the whole things, but I remember finding some of those that I read insightful and carefully-argued.
Paul Almond's site has many philosophically deep articles on theoretical rationality along LessWrongish assumptions, including but not limited to some great atheology, an attempt to solve the problem of arbitrary UTM choice, a possible anthropic explanation why space is 3D, a thorough defense of Occam's Razor, a lot of AI theory that I haven't tried to understand, and an attempt to explain what it means for minds to be implemented (related in approach to this and this).
