Why doesn't Yudkowsky publish the sequences--at least as an e-book? One likely reason: it would require extensive editing, not only to eliminate the inconsistencies that have arisen but, more so, to eliminate the prolix prose and filler that might make the postings entertaining to read on a blog (or which he just didn't take the time to cut), but which make for tedious sustained reading. A thorough rewrite would make a real contribution; Yudkowsky has a lot to say--but not that much.
