First of all, we have my two favorite carnivals: The Humanist Symposium #25 and The Carnival of the Godless #100.
Then a couple more that I'm adding to my reading list! The 8th Carnival of Sexual Freedom and Autonomy and Tangled Bank #114.
And -- as a special bonus -- Runtu has started re-posting the lost entries from his legendary blog: "Joseph's Left One"!!!
