Wicket moves to Apache
More info in the official announcement.
I have signed up as mentor to help with the incubation - although I do not use Wicket currently, it's been on my radar for a while and I'm looking for an opportunity to try it on a real project.
Wicket's philosophy (to put it simply) is to do everything in the Java space, taking advantage of the language's full power. This makes it a nice tool for people who are proficient in Java and don't need the "easier stuff" that other frameworks provide, which sometimes gets in the way.
