Comcast has revealed plans for a social discovery service called Tunerfish that it's been developing in secret with Plaxo.
The service will be more than a social gathering place among friends who link on using existing Facebook or Twitter accounts. It will use game mechanics to help users share what they're watching with other members of their social group--including things on TV, YouTube and other video sharing programs.
The product is in alpha testing and a public beta version should be available within a few weeks. It will first be launched as a website and dedicated iPad and iPhone apps.
