One question I have had for practicioners who work in Java "off-the-server" is whether or not they really layer their application architecture for their applications. You hear people throw that use case around for lightweight, POJO-based frameworks like Spring and Hibernate, but I always wondered whether or not that really happens.
If the response to that talk is any indication, the answer appears to be a sound "no". The five or so people that showed up all worked primarily on server-side stuff, and none of them cited any layering of this type within applications authored by their organizations. At a conference about Java off the server, that surprised me.
Overall another great day both at the conference and on the slopes.
