Nice read, thanks for the link.
I agree with the sentiment and the spirit. Blogs are indeed the modern pamphleteers. I don't think, though, that we should be content with blogs alone (and I'm not saying that is your suggestion). Our mass-mediated culture has a severe lack of patience for doing simple things like reading lots of words and the opposition can easily draw their attention with mindless blinky lights. Anything that appeals to the intellectual laziness of the masses is a distraction. We need our own blinky lights to compete with theirs.
