I just realized the power of Twitter. I've been a member there for almost a month, yet it took me until today to fully appreciate what Twitter can do for society (at least, the society capable of utilizing it).
I first started thinking about it the other day when I learned that a Zimbabwe group was using Twitter to scrutinize the Zimbabwean elections, and that it was receiving international attention because of its coverage.
Then, about ten minutes ago, it hit me. I was responding to Meghan McCain's most recent Tweet (what Twitter's "posts" are called--all required to be 140 characters or fewer) (at the time): "Because I keep getting asked...... A few reasons why I consider myself a Republican: I believe in less taxes and less government spending." My response to her was "I've been wondering about that as well. You sound like a Blue Dog Democrat... :)"
And then I realized for the last month, I've been communicating with people like Meghan McCain, Rachel Maddow, and R. T. Rybak. Even though these people choose to respond to only a few responses (if that makes sense) each day (and we really can't ask for more--after all, if we had thousands of followers, we'd have to pick and choose, too), they DO read our responses, our questions, our criticisms, and yes, occasionally, they respond to us.
Think of how much power Twitter has to connect people! Possibly more than any other social networking site so far.
If you're not yet using Twitter, I suggest you start. It's an unbelievably innovative system.
