See Twin Cities Meteor Developers Group. A kitchen sink application is a sample application that is used to copy and paste from when making real applications. We are building one to gain experience with Meteor, and so we have the application to use. For now, we meet Sunday afternoons and Wednesday evenings at the Common Roots Cafe.
We believe in jumping into the deep end of the pool and thrashing. As we go, we will figure out how to merge our two user groups, how to share our code, and how to report lessons learned.
