Adam had a long talk with me about his rift with Bono, but he veered off and started talking about the major rift Jick was having with Larry.
Seems that Jick thought he was a better drummer than Larry (and better looking), and Larry almost ran down Jick with his Harley. Things haven't been the same between those two since.
Jick has then vented his frustrations through his posts on Interference.com, while Larry has taken the more productive approach of making great albums with his band, now that Jick will never be the fifth member.
Since then, Jick has been trying to start infighting, whispering rumours to Bono of how Adam doesn't like how he smells after smoking, and then whispering to Adam that Bono doesn't like the fact that Adam no longer drinks with the band.
Hence, the current rift.
