Antony Mayfield links to Google's "mind blowing collection of creative ideas". I just skimmed through, but you could spend days exploring all the web apps listed there.

All this inventive technology is being made available to just about anyone with a web connection. How does it compare for engagement and collaboration with anything inside the firewall of organisations? I've argued before that, over the last few years, the technological advantage has shifted massively away from companies to individuals. I think we may only have scratched the surface of the impact this will have.
