Brian McLaren, Dan Kimball, Leonard Sweet, Rob Bell - all Emergent leaders who've moved into more of a "coach" position. Who are the New Emergent Leaders today? Lots of names you may not have heard of. Leadership Network (the original Druckerite emergent machine), is hooked up with a number of the Next Gen emergent leaders. The Nines Conference is one of many emergent conferences and names you can mark and avoid.
I highly encourage you to begin your research into the Emergent Church Movement by clicking on this White Paper on the Emergent Church Movement.
