Glennzilla has a good piece.
I usually don't scream quite as loudly as I used to, because I don't have to. Back in the early days you had to make noise to be heard. Now that the internet is much more all linked up, one doesn't have to be quite as noisy. If you have a good point you can probably get an audience for it. I'm not making an internet-as-meritocracy argument, I'm simply saying that stuff can be linked and relinked and twittered and facebooked in a way which didn't happen back in the "old days."
