Of Microbes and Men -- Clostridiophile regularly responds to posts.
flinging dust -- There's usually something humorous posted here, including on Ray and his commenters.

Friendly Atheist -- Posts on an array of issues including news items, several on Ray.
The Ranting Student -- A recently started blog with several posts on Ray

Also, there is a blog called The Seeker which has posted twice on Ray. I thought I'd link to their first post here as it's the person's introduction to Ray Comfort's logic (such as a Boeing 747 contradicting logic).
