Well, I guess I ain't gonna be inventing THAT one!
It has already happened. Blog it forward is already in motion. What form it is taking, I do not know. My own idea was pretty simple: You learn to blog? You teach three other people how to blog, and then get them to teach three people...on down the line. I am currently teaching two people, one of whom has agreed to teach three, and the other will probably do so as well.
The Charlotte Observer has been running a series on "Pay it forward" and so the concept is quite familiar here. "Blog it forward" should also be a fairly easy grasp.
Already, North Carolina is in the vanguard of blogging. To exponentiate matters...blog it forward.
