I feel the biggest hole in technical/small social groups vs. church groups is the lack of permanency. With most church organizations there is a built in way to bring fresh people in to associate with the church, and a dedicated place to meet that you can expect to be there with modest assumptions 10 years from now. A technical group is generally completely nomadic, they have to do a lot of work to bring people together. The glue that keeps them together is flimsy as well- a tech group is less likely to keep someone who makes a drastic change in occupation (IT to a brewer) compared to a church. The major lack of easy association to the group is something that is hard to replicate in the nonsecular space. There is nothing strongly compelling about a group that's focus is too general, and the difficulty to bridge the gap from outsider to inclusion can be too high for a group that is interesting.
