I haven't read that article, but I don't really care if people disagree with Bono. That's their opinion. But the problem I do have with many of them is that they can't just disagree with him, they have to be snide and nasty about it, like making remarks about it being foolish for some rock star to be involved in these important word issues. These people rarely ever acknowledge that Bono is widely recognized as a true expert on the problems in Africa. This leads me to assume that they either don't know about Bono's expertise which means they actually know little about the subject they are criticizing him about, or they do know but will not give him credit for his expertise which means they are simply jealous.
Anyway, congrats to Bono and Mr. & Mrs. Gates. They all deserve this honor.
