There are people out there that will, very unfortunately, be dismayed that Bono isn't dead yet.
Do you remember the 'Make Bono History' campaign around 2005? The Anti-Bono Brigade were out in force having gotten fed up with the way he was promoting 'Make Poverty History' / African Debt etc
When SOI/I&E tour was released / tour dates announced, there was a backlash in some of the media outlets via the 'comments' section. I remember reading one particularly sickening genuine comment someone posted about the then upcoming I&E tour. The online newspaper article describe the tour as electrifying and explosive (or words to that effect) and someone posted that they wished a concert would end in an explosion and there would be no more from Bono. Given that this was pre Paris/pre Manchester, that was very, very chilling. I think it might have been one of the British rags' websites.
Bono does read internet comments about himself, just go and check out his acceptance speech at the Woman of the Year awards last December and you'll see that he takes self-parody to some extent. But sometimes you can't do that.
Maybe this is a way of saying, yeah look I'm not dead yet. If it is, I hope that the truth is outed because it would actually help Bono rise up above his critics now, rather than us all debating/speculating what it was that could have killed him.
Long live Bono, Godspeed.
