Cedric Beust has blogged on the AOP Panel at JavaOne, which showed the capacity crowd that AOP is taken very seriously and considered in very pragmatic terms by a lot of people these days. Panelists included Gregor Kiczales, Graham Hamilton, Cedric Beust, and James Gosling.
"The AOP panel at JavaOne was a big success. Maybe it was because of the provocative title ("AOP : The next big thing or giant leap backward"), which was concocted by the mischievous Graham. Maybe it was because James draws a lot of attendance. Or maybe, just maybe, it's that more and more people are getting extremely curious about AOP."
