Surrounded by a cloud of Christians

I have been a casual observer of some movements, on the internet in particular, that at first seemed to be powerful in potential to impact irreligious people for the Kingdom.
Then…nothing.
*crickets*
At first it was really exciting. 3000 people read that guys blog. 10,000 people tuned into that churches live stream. 40,000 people follow that pastor on Twitter. The common theme here is that almost all of the people showing up are Christians.
I think that this is all cool and everything, but it does beg the question; why can’t we create the same movement and energy in an evangelistic direction?
There are Christian ghettos all over the world, and the biggest ones are now on the web.
