I spent a while yesterday evening trying to get to grips with Twitter. One of the most interesting things is its searchability through sites such as Twitter Search. I searched for "medical education" (without the quotes) and managed to find a few of the people I had come across on other sites. I could therefore access their blogs and twitters although it is harder to find networks on Twitter. But I did find tags to the Medicine 2.0 conference so that brought more links to interesting people and interesting blogs. I've added those blogs to the list on the side.
Now, beyond acting as a database in this way, I'm not so sure how useful it actually is. But I will learn!
