Another good presentation re Web 2.0. Good examples and case studies help drive the message home.

A presentation given at the Social Network World Forum in London, 9 March 2009. The topic was about justifying social media spend in a recession to ‘internal clients’. Brilliant.

An excellent introduction to the metrics of Social Media. The presentation is a it out of date, but nevertheless relevant.

I suggest you download it so you can read the text better.
