Neil Cole has written books on reproducing disciples (Search+Rescue), leaders (Organic Leadership), churches (Organic Church) and now, with this new book; movements (Church 3.0)
Neil is well qualified to do this, as he is perhaps, one of the few people who is actually experiencing a gospel movement of people coming to Christ from the harvest in the West.
He highlights different social groupings: 2-3, 5-7, 12, 70, 120-150, 500 and how each size functions best in unique ways. For example:
2-3 are best for radical discipleship
5-7 are good for shared leadership
12 is the family (simple/organic church)
70 is good for training
120-150 relate as a network of families (15 simple churches)
500 are good for conferences
I have written a page on Being Church: All Shapes and Sizes that describes some of the ways we currently meet reflecting some of the observations and experiences described by Neil in his book
