' The next time I enter the blogosphere it will be about music... far more appropriate for a rockstar. ' Bono winds up his week of blogging for the FT.

'Thanks for reading. I've enjoyed the week at the service of the FT. The next time I enter the blogosphere it will be about music - far more appropriate for a rockstar. It's time to shut up and sing, but it was rock and roll that taught me the world was more malleable than anyone knew, that it could be shaped by kicks and caresses, but better by reason. What I didn't know was that numbers can be more important than words.'
