If I didn't have an email address, and Post.fm claims to re-invent email, and yet Post.fm requires an email address, does my head explode when I try to connect

If I didn't have an email address, and Post.fm claims to re-invent email, and yet Post.fm requires an email address, does my head explode when I try to connect the dots? At some point obscurity stops being cool. I think I reached this point just before I left high school.
