Ahtzib, a new commenter, has great detailed thoughts on the second post on Lovecraft and race, and the post on alien skepticism that are worth going back to look at.
He also has two great blogs on these topics. First, Miskatonic Museum has interesting thoughts on the Lovecraft universe. Recent posts include a discussion of the sources that Lovecraft used to learn about cannibalism, the geography of Lovecraft (i.e. - where exactly is R'lyeh?), and artifacts that look an awful lot like Cthulu. The second blog is Spooky Paradigm, which is dedicated to UFOs and cryptozoology - it seems like a skeptical, speculative, interesting approach he takes to it all (which I think is precisely the right balance to strike).
Both of these blogs are on my blogroll now, and if anything interesting comes up I'll repost it here.
