Azoff Done Tweeting?

Irving Azoff and Twitter: is the relationship souring?

It appears the Live Nation Executive Chairman has deleted all of his posts since Aug. 8.

Gone are tweets about Barry Diller, U2 manager Paul McGuinness and everything else from the beginning of August.

It could not be confirmed at press time what is going on, but it has been noted that tweeting is an unusual activity for a company executive, who usually makes sure his or her public statements go through the legal department first.
