I recently gave a webinar entitled The Economics of Free. My host, Vindicia, is the leading provider of SaaS billing and marketing systems for digital content and services providers, and it was a lot of fun to field questions from their customers, who include dating sites, gaming companies and content publishers, as well as application developers.
They have been kind enough to make the webinar available to the public. Feel free to check it out–and also take a look at Vindicia–they have a great offering.
