Neal Stephenson's latest book sorta deals with this.
One way the characters in the book got around the huge signal to noise problem was by using editors who were paid to filter it out. Different people could afford different qualities of editors and that had effects on society.
It's a pretty small part of the book, but it's very interesting.
I had totally forgotten about that part of Anathem!
