In case you're looking for me on Facebook and you think to yourself, "Hey, maybe he's using one of those newfangled handles," or maybe you didn't think to just type in my name
I am at http://www.facebook.com/davidwertheimer now. Wow.
(George got to Werty ahead of me. We seem to share the space--I have it on Twitter and del.icio.us and Metafilter, he has it on Flickr and Digg. Neither of us know who the YouTube Werty is, though.)
