First, I'd like to clarify that this isn't just about building your e-fame or competing for more followers. It's about meeting new people and building new friendships, as well as strengthening the bonds you already have.
Add me, and anyone else linking to their Twitter pages in the comments area (or, at the very least, visit them), and then drop your link. (Please don't be greedy- you have to link and add others in order for this to work!)
