When it comes to Twitter, I suppose I don't really follow the unwritten law of "you should follow anyone who follows you". In fact, I'm really picky about who I follow.If I check out your page and you've posted too many times that day, I won't follow you. If you haven't posted enough, I won't follow you. If I don't like your display picture, I won't follow you. If you have all tweets with no replies, I won't follow you. If you're following too many people, I won't follow you.Too bad if you happen to have a bad day or exhibit some once off behaviour. Chances are I won't check you out a second time.I always judge books by their covers. Does anyone else? And do you ever stop and think about what your profile looks like right now? I know I don't do it enough....
