Writing about web page http://twitter.com/home
It’s the worlds most basic social-networking app. Text or IM it your status, it updates. Build a network, and you get updates on what everyone else in the network is doing, either by text, IM, or over the web. And there are APIs. It’s 1% of facebook, but with mobiles.
The next facebook? I can’t decide. Facebook Mobile does all this and more, but only appears to work in the US. O’Reilly seem to like Twitter, though whether that counts for anything I don’t know. I like it’s ‘do one thing well’ attitude though.
update 13/3/07 It doesn’t seem to be coping all that well with what I imagine is the rush of traffic from SxSW at the moment. Sigh…
