If anyone from here follows me on twitter - and thinks it would be good if that were reciprocated, you are going to need to let me know, especially if the user names don't match what you have here. I'm getting lots of follows now from people who are scammers or whatever. I think they are fishing around for people that use clients that will autofollow back, stuff like that.
I got my first reply on twitter the other day from someone I don't know. They were replying to something they found via search - it wasn't someone following me. This is where it is going to get interesting. I'm waiting to see when spammers start using this. Depending on how things go - it could basically make twitter completely useless. (insert already useless jokes here)
