Thanks for the introduction to Twitter Commons! I've used Dropwizard in the past and loved it. It seems like the shared libraries of both frameworks -- Jetty, Jersey, and Jackson -- provide them with an equally strong foundation. Guice seems to be provided by default in Twitter Commons whereas it's provided via a separate module in Dropwizard, so that's more or less another commonality between them. Can anyone describe differences or pros/cons between using these two frameworks? (Similarly, who was being referenced in the phrase "an opinionated framework that forces certain patterns on you")?
