Antisocial people are often quite charming and adept at making superficial friendships. You do not sound antisocial. Asocial perhaps, but not antisocial. I also agree that it does not particularly matter, but no, you are not antisocial. You do seem to be introverted.

let me ask you this silly question - WHAT do you talk to people online for hours about, and why cannot you talk about the same things with RL people??
