This is kind of old; I forgot to post it when I intended. But they're still worth reading/remembering...
Donald Miller writes about how infighting will kill the church - http://donmilleris.com/2011/02/17/how-infighting-will-kill-the-church/
And JR Woodward answers the question of how a missional community is different from a bible study on the verge website - http://www.vergenetwork.org/2011/02/23/jr-woodward-whats-the-difference-printable/
And, as much as I hate to link to a beliefnet blog, Jason Boyett catches us up with Thoughts About Rob Bell, John Piper, and Justin Taylor - http://blog.beliefnet.com/omeoflittlefaith/2011/02/thoughts-rob-bell.html (this is somewhat related to what Don Miller is talking about, I think).
