I do have a facebook account. It gets checked oh...about once every 3 or four months. Which reminds me, I should probably go log in for a minute over there. Anyway I know other people use it, but I have never gotten all that into it. (obviously) Whatever pushes more traffic your way though, you should use all the tools you have.

And to prevent image abuse, I'm not going to upload images there... only via linking
