I don't suppose you've got any notes or slides from your MSF talk have you? As someone who's a blogger and trying to market a product, I can see both sides of the problem to an extent. I don't like being spammed by marketers who are going for quantity of emails sent rather than quality, but it's difficult to work out whether a blogger is likely to be interested in what you're offering and (maybe more importantly) happy to be contacted. I don't think that you can hold up your posting about Gia's film as successful marketing because surely that's just you talking about what your friends are up to?
