As a wise old sage once said: "So. Today I am a blogger."
Actually, I've been blogging as a contributor over here for a while, but I try to keep those posts limited to things that I hope will amuse, educate, or in some other way be moderately interesting to the other contributors on that site. Blogging here doesn't mean I won't blog over there, too.
Luckily, I have no such restrictions here, and I can blog about pretty much anything, even if no one ever finds them the slightest bit interesting.
