Todd Levin on Twitter
Todd Levin has the following to say about Twitter while while writing about South by South-BEST:
Every year, SXSW Interactive attendees collectively discover a piece of social technology that quickly becomes integral to the SXSW experience. A couple years ago that technology was the photo-sharing site Flickr; this year it is Twitter. Twitter is a very simple concept to explain. Imagine there is a tiny invisible girlfriend sitting on your shoulder, constantly whispering in your ear, demanding to know what you’re thinking at that precise moment. Now, imagine you decide to answer every instance of her question by sending a text message to her, and all of your friends. That’s kind of what Twitter is like, and we’re positive it’s here to stay!
I don’t get Twitter. Sure, I’ve got an account, but I don’t get how it’s useful. Maybe I’m not social enough? Maybe I’m too old?

I don’t get Twitter either. Maybe we just don’t have enough friends? Or maybe we’re just not cool enough.
Seriously, what does Twitter accomplish that a blog doesn’t aside from letting people keep tabs on you where ever/whenever you are?
