Dave Winer is digging into the implications of services like Twitter and how they provide the infrastructure for extraordinary unintended consequences. Given Dave’s history of creating things that fundamentally change the way we do things (outliners, RSS, podcasting) I fully expect we’ll see something exciting from his work, even if we won’t know it’s exciting at first.

His recent post points out that Twitter is all about trivia. It fits into the new economy/ecology of the long tail, narrowcasting, tagging and as David Weinberger reminds us, everything is miscellaneous. I relate it further to crowdsourcing and our own efforts at PodCorps.org.

We’re getting away from thinking that success only comes from things that are important to everyone — mass audiences. We’re actually  getting away from narrowcasting, too. That was a one-way idea that broadcasters could offer targeting content to narrowly defined demographic groups. What we’ve learned is that those groups can and will create their own content and that it will be much more interesting and valuable to the members of those groups. I wouldn’t be surprised to learn that for people who use Facebook, Twitter, etc., they already receive far more aggregate value from (and spend more time interacting with) their social networks than with traditional media. Perhaps someone can identify the dates and events at which we turned that corner.
