Speaker talked for a very long time. Part of the purpose of user groups is to be able to network, learn about what is going on in your community, etc. Given the length of the talk there was little time and little energy left for networking. That said, I found the talk interesting enough. The speaker needed to provide some higher level "pictures" to go with the details - this would help to bridge the disparity in knowledge amongst the audience given that some where relative newbies to this tech and others were quite familiar with it.
