Contact me for any reason. I mean it! Want to work on something with me? Want to hire me for a project? Interested in what software I use? Whatever, I'm chatty, just hit me up and I'm almost certainly going to respond. Twitter's a good option for talking to me since I spend way too much time on there.
(Note: Replace ★ with @)
I also have AIM, MSN, Skype, you name it.
