Well, at the how to Rawk panel, Tantek was touting the wonderfulness of Twitter. So, I gave and signed up. What is Twitter? They say:
A global community of friends and strangers answering one simple question: What are you doing? Answer on your phone, IM, or right here on the web!
It’s great for something like SXSW. Wanna see where everyone is headed for lunch? Look at their tweets. Wanna know what Jeremiah really thinks of that panel? Find out in real time.
I guess it’s kind of like a public IM that is permalinked like a blog. You can easily “subscribe” to people and get their latest updates to whatever device you want. It’s really device agnostic, since it is just plain and simple text. Do it from your phone, your browser, an IM client, whatever.
Twitter is brought to you by Evan Williams, the brain that brought you Blogger and Odeo.
