No, we haven't deleted any comments today. They're disappearing all on their own* (including at least one of mine).
We have a rather, um, liberal commenting policy. In over five years, I can count the number of comments deleted on one or two hands. This of course does not include commercial spam which we delete anytime we see it.
Sorry for the inconvenience! Hopefully Blogger will be back to normal soon.
* Note: We aren't completely ruling out some involvement by AG Tom Corbett. (That's a joke, Mr. Corbett. Please don't subpoena us!)
