Dr. GUI a compilation?

via Chris Sells: MSDN's Dr. GUI, is now blogging. So I gotta figure out how that works. Dr. GUI is like a compilation of a bunch of MSDN folks, right? So who gets to do the blog? Is it a free for all? Well, I'm sure it will be fun, informative and full of all the silly puns we have become used to!

Actually, I don't think Dr. GUI is a compilation. At least, I've met someone who claimed to be Dr. GUI (even had it on his business cards), and I have no reason to doubt the claim. I suppose that there could be more than one "Dr. GUI", but that wasn't my impression from the meeting.
