Nice to see a 1.0 release. We've been using Dropwizard for various public and internal APIs for a couple of years and have been very happy with it. The components (jersey, jackson, coda hale metrics) are all very pleasant to work with, and generally have low-ceremony APIs that feel as productive as the ruby or python equivalents while providing the performance and operability of the JVM.
It's not the fastest or most scalable option on the JVM (that would probably be something netty based) and the API is an awkward fit for anything streaming or asynchronous, but it's the best thing I've found for its niche.
