Ok, so I am a little late... but I am now fully "Twittered."
I learned about Twitter a while back, and created my account, but never took much time to really set it up. I wasn't really sure why anyone would really care what I was up to. Today, however, I needed to get a hold of Steve Dembo, who is presenting the luncheon "keynote" at our Summer Experience workshop next week. I wasn't sure about his email address, and even though he was showing up as available on my IM list, he wasn't responding. Well, I knew Steve was a Twitterer, so I dug out my info and logged in. At first I wasn't to sure how to add him to my Twitter list, or post or send a message that he would see, but in a few minutes I figured it out. I was surprised to get an almost instant reply from him in his car!
Of course I then spent the next hour culling through his 180-plus contacts to locate mutual acquaintances, and their mutual "Twitterees" and so on -- and I began building my Twitter list. I've added 34 to my list so far, and (just a few hours later) 10 Twitterers have already responded in kind. What is intriguing is the conversations that occur. It's somewhat like a "live listserv" -- post a thought, question or comment, and someone is back atcha in no time. I have also discovered Twitterific for monitoring the postings.
