I swore it would never happen to me. I tried to resist the dark side, but Wil Wheaton was there, so it wasn't always easy. I actually joined the rest of the herd and opened a Twitter account. I haven't really figured it all out yet, but there it is. I don't really understand why you do the @ thing before someone's username, and I don't really understand what that signifies or whether they know that you do it and how they know.
My Twitter thingy is LizzShep. I don't know what I'll do with it, but I was already "following" three Twitter users by looking at their Twitter pages to find their new tweets, so I figured this would just simplify things. I also keep hearing about how great it is for marketing, and I've been forced to write several articles about using it for marketing, so there are also possibilities there. We'll see. If it's just a time sucker, well, it will have a lot of company.
