A PowerPoint from Karen Blakeman, presented at a recent event: Web 2 - the truth behind the hype. It is also worth checking out other presentations on her slideshare account, e.g. the 2 uploaded before that are "Buisness research: Web 2.0 is not an option but a necessity" and "Twitter for business: an essential marketing and research tool"
