Is the blogosphere beyond control?

the evangelical outpost: talks about the different types of political blog and then says:

“The blogosphere, after all, is still a grassroots medium. And, like all such organizations, it’s ultimately beyond the ability to be controlled by a central figure.”

I am not sure I fully agree with that statement. People like instapundit do a good job of controlling the blogosphere, and I am reading Mandellas book- in the end he sure led the ANC which was a grassroots organisation.

People like Billy Graham have even managed to galvinise groups of churches which are surely often grassroots organisations that you might expect would not be led. Or for that matter what about alpha…..?
