The solution to monetising this cacophony of content is by structuring it. By having a gatekeeper to keep the truants and chancers out, by setting a few standards, and by commissiong content and choosing the best of it. Editors also no longer need to be (nor should be) traditional media people, but come from the same stock as New Media. Over time, the mass media will be New Media, and the number of 'expert' commentators will come from the mob, not from the newsroom. It will take time for this to happen, but the point is, it IS happening.
One of the reasons it will take time is because current journalists and editors are so resentful of the 'untrained' (code for uneducated in their particular field, as though one needs to do a writing or photography course to write or take photographs - as they did).
