Emerging Church - yes, there are cons!

I've found a link in Knightopia to a Jason Clark post about pros and cons founded in emerging church movement (Love/hate the emerging church).
Most of pros come from freedom and simplicity of doing church, it seems that the cons come from the fanatic people that started thinking that this is THE way of doing church and annoy others that are sincere too but not as "post-modern", other annoying think come from the mind that everything worth, we in Brazil call that "zona", i.e. a great mess.
I think this is a very need and important assessment to be done right now in order to not change a way of doing church for another kind of legalism.
