Guess who's blogging from the UN for the Financial Times?
Well, yes, Jeffrey Sachs is. But he's sharing an account with Bono.
It's a chance for Bono to actually expand on some of his thinking - to be fair to him, in brief TV interviews, he's doomed to come across like a glib ingenue who is over-fond of hanging out with the rich and powerful, because TV can't really cope with complex thoughts. So, given a blogging platform, does Bono manage to convince the world that there's more to him than some well-learned briefs, a lot of goodwill but something slightly empty at the heart of his efforts?
Perhaps it's unfair to expect Bono - a stadium rock lyricist, after all - to be able to express himself in anything other than slogans.
But surely he could steer clear of the cliche?
