Twitter (!)... Can someone tell me what it is about and what people are looking for there?

[modulo_function]

I like Twitter. It's usefullness for me is all in the people or groups that I follow.

I follow

Paul Krugman at NYT
a couple of different NASA sites, especially the APOD, Astronomy Picture of the day
SFExaminer, the newspaper here in SF
Stever Martin, the comedian
JimmyFallon
Roger Ebert
Many science, economics, and social commentary sites like Mother Jones, Salon, Slate,
...Scientific American, Gizmodo, Cnet....


Various government and commercial sites that I'm interested in.

I log on and look through the tweets to see if anyone has posted anything that I might be interested in. If so then I click it to read it.

Two local transit systems I follow: BART and CalTrain.

Following me won't do you much good since I don't really have anyting to say. However, if you follow me then you get to see a list of who I follow and can, if you want, follow them too.

For me, it reminds me of a teletype in a news room that's bringing in news.

My recommendation:
It usefulness is all in who you follow. Use the search feature and search for things like
'aviation', 'flying', 'Nasa', 'science', etc....Then follow some.

It's easy to follow and 'unfollow' someone so start following and you can winnow your list down anytime. Also, when you follow someone Twitter shows you who you both follow and also suggests others that you might want to follow.
