OK, so I've no desire to read anyone else's tweets, but I've been thinking that it's a good medium for saying 'hey, check this paper out', which is often all I want to do. So I've set up a feed, and put that last post on it. I think it's called @gentraso. We'll see if it's as colossal a waste of time as I've always believed.
9 July update. That really was a very graceless post, wasn't it? On poking around twitter, I can see that there's a some interesting stuff, and I can see how it's potentially addictive. I've still not signed up to follow anyone yet, though (though I may). And I'm still not sure where all the time for this stuff comes from.
