Forgive me if I requote Tony Blair:
"But if we follow the principles that have served us so well at home - that information generation and sharing - must be in the hands of the many, not the few - if we make that our guiding light for the global economy, then it will be a force for good and an international movement that we should take pride in leading."
This seems to me to be the essence of Web 2.0 - the buzzword which is sweeping the world. It says that by working together - sharing information, links, comments, linkbacks, and by making software open-source and generally available - everyone will benefit.
Imagine a world where the productivity of software developers grows exponentially as they put new systems together out of parts sourced from their peers. Imagine a world where you can publish information about new products and get feedback and ratings from your global customer base. Imagine a world where democracy means that the whole country could vote on an issue rather than someone representing you and thousands unlike you.
It's a powerful concept and companies/organisations/governments that ignore it deserve to be left behind. Only the information-enabled will be truly agile and only the truly agile will survive in our turbo-Darwinian world.
Web 2.0 - it's like the web but democratic.
