if you post anonymous then your too stupid to post on this site. when you create a profile your already anonymous. So unless you put your real name or put a real pic of yourself, nobody can find out who you are. So what is the point of posting anonymous? it is so irritating.
You would still be anonymous but your questions would show up in their news feed or be recommended to them. I believe allowing someone to follow you, lets them see more of your profile but I'm not entirely sure.
