When you first sign up for a social network such as Twitter you aren’t going to be popular. You might even feel like there’s a huge party going on, but you just can’t find it or don’t know how to get involved.
You simply have to get over that.
Proactive follow others and engage in conversation; in doing so, you will start to see the value in the conversations that take place and also gain followers.
And if you don’t “get” Twitter at first it’s ok. I picked it up, put it down and then picked it back up again. Look me up, I’m @ryanshell.
