I've felt this in my gut, and good to see writers confirming it.  Here is a good article/interview on the reformation of the church occuring through social networking.

Here's a great excerpt on the effect on ecclesiology:

I really do see that the digital culture is contributing to a new distributed ecclesiology.

Reformations correct excesses of a previous movement and help evolve the church in a direction truer to Christian roots. I’m a Protestant, so for me, the 16th-century Reformations made all kinds of improvements. But they also tended to participate in the modern movement toward separating and segregating people from each other, communities from each other and the church from the world.

The medieval cathedral was engaged in the world around it. After the Reformation, it became a component of a largely secularized society. The church was the box down the street where you did religion.

What social media has done is go back to that pre-modern ecclesiology of church and faith being embedded in everything we do. But it’s not driven from the top down. It’s driven from the bottom up. It’s not coincidental that the emergent church movement developed just as social media developed.

These aren’t accidents. We’re moving to a widely distributed ecclesiology where ordinary believers are sharing their faith and claiming religious authority in new ways, and that’s impacting the institutional church profoundly.

We’re realizing the priesthood of all believers in a powerful way that says, “Yes, there are people who do sacramental ministry, and that’s important. But there are other believers whose priesthood takes other forms, and they’re equally important.”
