SharkScopers is a Drupal 6 site that allows online poker instructors to sell screencast tutorial videos. The first two minutes can be viewed by anyone. Users can purchase credits that unlock whole videos. Instructors then receive a cut of the profit.
Jonathan Brown from Blue Droplet Media in Edinburgh, Scotland, has been helping Mike Jonas from SharkScope in New York develop the site for more than a year. It uses Jonathan's Blue Droplet Video module extensively.
Mike had done a lot of research into what system should be used to build the site. His primary motivation for choosing Drupal was so that Blue Droplet Video could be used. He was blown away by how BDV integrates with CCK and Views, allowing the fundamentals of the site to be created with great ease.
Jonathan and Mike have very well defined roles within the project. For each task, they consult via email and Skype to construct robust specifications. Jonathan then implements the required functionality. A release early, release often methodology is used, allowing the site to innovate rapidly.
The fantastic theme was created entirely by Mike as a Zen sub-theme.
