Dave Pollard on the fatal flaws of first generation Social Networking sites and tools.
They're built with a pre-designed, set content architecture, and centrally-stored content, instead of harvesting content that individual users already have stored, in different ways of their own choosing, on their own machines.
They're being populated just-in-case, with all kinds of content that people with lots of time on their hands see fit to contribute, and no content from the very busy or technologically illiterate, rather than just-in-time, with content being accumulated only if and when there's a demand and need for it.
They're badly over-engineered, ranging in complexity from challenging to intimidating, so they take a lot of time, energy and intelligence to understand and use properly, and hence drive most potential users away.
