I'm giving Twitter another shot.
I tried Twitter a while back and couldn't get excited about it. I didn't know why I'd use it, or how.
I just got back from Open Source Bridge 2009, in Portland, OR, where it was all the rage. (The other things most attendees were into were Ruby and git.)
"Okay," I said, "let me find someone who gets it, and I'll just ask how to approach it."
Ms. Amye was willing to be my evangelista, so I logged in, set up my account, and am now following a few folks that I met at the conferences (#osb09 is the Twitter "hash code"). I've even tweeted.
