You don't care how you look? Of course you do, otherwise you wouldn't need to record yourself in 1080p so you can watch yourself over and over again at a later date. You can't get much more into yourself than that. It's ok to admit that you do care about how you look.... You just have really bad taste, that's a whole different thing.
Oh and when GoPros first came out and everyone was wearing them On their heads, I was the guy who said "that looks completely stupid, I'll wait for someone else to come out with a better option" ....and low and behold.. It didn't take too long.
