OK, I totally lost track of what day I'm on in my experiment, but I'm pretty sure I'm not at 21 days yet. Still, I can honestly say I'm now a Twitter addict. Do you think they have a program for this at Promises in Malibu? Because the first thing I do every morning is check in with Twitter. Whenever I'm switching tasks, I check Twitter. Twitter is down right now, and I am shaking.

Well, I'm not really shaking. But I miss my Twitter friends and their Tweets! And honestly, Twitter has turned out to be much more than just a social network. I get a lot of professional development out of it. I find articles and announcements from folks, as well as tips and advice. Sure, it's all arriving in between Tweets about what User A is having for lunch, but I actually find that charming now.

I would publish a bunch of lessons learned about how Twitter can be useful, but someone smarter and wittier beat me to the punch. Check out the "The Top 5 Ways Smart People Use Twitter." It pretty much sums it up.

So I guess all that's left for me to do is to pick the next technology that I will tackle for 21 days. Anyone want to be my Second Life coach?

P.S. Thanks to Beth Kanter for the inspiration for this.
