My new website for all stuff related to Wicket is getting some traction: the number of visitors is rising, though not at the same level this one has. The goal of wicketinaction.com is to become an official place for Wicket Community related news, not just book news. Expect release announcements, events announcements and articles to be published on wicketinaction.com
I suspect the new wicketinaction.com website will become more popular now that Igor Vaynberg, one of the most prominent committers for the Wicket project, has pledged to start blogging on wicketinaction.com.
I'm expecting quite some dynamite from mr. Vaynberg—he's responsible for the awesome repeaters package, spring integration and salve (Salve solves the problems that cause anemic domain model anti-pattern and brings back object oriented programming to the business tier).
