There's a whole conference dedicated to aspect-oriented programming. The AOSD (Aspect-Oriented Software Development) conference is put on by the AOSA (Aspect-Oriented Software Association).

The 2012 conference is on March 25-30, in Potsdam, Germany. A five day conference on AOP? Wowza. But wait, there's more. You can also attend FOAL (Foundations of Aspect-Oriented Languages) while you're there in Potsdam on March 26, where Eric Bodden will be keynoting.

All things considered, I'd really like to go, but I definitely can't.  Maybe next year decade, after I save up enough vacation days and learn some German?
