Tell me something you're interested in and it's likely I am too. Leave me a comment, let me show you. (And I am committed to replies; if you don't hear from me it's because I missed you.)
There is nothing about me you need to know, with the exception that if you have a high opinion of yourself (i.e. think you write the best fic ever, tell me you're a member of MENSA, too sexy for LJ, so funny you're wired for humor, unable to bear the sound of your own awesome, defensive like a boss), then I would skip over you during speed dating.
Dude, check out Newton's apple in Einstein's rocket elevator.
