This is nothing new, but there are still people out there to whom Web 2.0 is a bit of a mystery. What exactly is it, and more to the point, should our business care about this stuff? Or, as I have heard senior executives argue, is it just another bubble, a distraction to let others waste their time, effort and money on. In an attempt to challenge this assumption, I’ve used a model with a few sceptical clients to hang some structure on. This is central to the below presentation that I’ve given to a few financial services organisations. It discusses what Web 2.0 is, and towards the end describes what it could mean for their on-line retail bank website. (Thanks to Duncan Cragg and Prashant Gandhi for some insights).
