So ... I didn't really mean that in Twitter everyone should follow everyone else.
My personal rules if someone follows me are:
1. Check them out
2. Make sure they aren't a Twittermouth. More than, say, 30 tweets a day gets very close scrutiny.
3. How much is that person in conversations and how much are they just spouting
4. Do they look thoughtful?
I am more willing to give people the benefit of the doubt because I can just unfollow them later.
The main point of that post was, the goal isn't to run around getting people to follow you - it's to have conversations with other people.
So, please stop hitting me!
