Steven Tyler is Idol Judge

In the quest to remain fresh and watchable for a public with a short attention span, American Idol is doing a major overhaul of its judging panel. The article in The Straits Times of Friday, August 20 2010 (Life, page C14) justifies the selection of Steven Tyler by emphasising his entertainment value: he "lives to be in front of an audience... can be counted on to deliver - maybe even sing - witty, Little Richard-style verdicts on the performances" etc. So, judging is about .... entertaining? There is mention of the hard rock element that he will introduce as opposed to an Idol history of soft ballads: a suggestion that the next winner may look and sound different from the previous ones? It depends on the choice of the other two judges. Any predictions or suggestions?
