I was in the newsagents recently and came across a magazine with a pertinent message - the front cover screamed Magazine 2.0. It was an experiement by the Anthill Magazine to secure user content and even run a contest to design its front cover based upon user submissions.

How about that! I had to buy the magazine of course as it was a hardcopy version of what the Alinement Network is attempting to do. There are differences and in a way it is a lot more aggressive to apply the Web 2.0 principles to a traditional magazine publishing model .... but there is no stopping the momentum of User Provided Content.
As in the case of Anthill's experiment, I personally consider some coordination necessary in sifting and sorting the user content in order to provide some value-add that can then sustain the momentum of user contributions. The difference between data and information comes to mind here - content is a whole lot of data but it takes some organizing and shaping to make it more easily accessible and so valuable. Who knows, with some luck you might even be able to create some knowledge.
So that would say that at heart I am a control-freak and, ultimately, not a believer in the self-organizing principles espoused by those with a more agile bent. It's not that I don't believe that amazing things are not possible with simply trust in the "wisdom of the crowd" .... it's more that I fear the probability of success can be too low and don't have the patience (or is it lifespan) to take a simply evolutionary perspective of success.
