A very important post on Joost from NewTeeVee in this post. Joost is one of the first Web 3.0/Semantic Web companies around integrating RDF in their P2P TV product. Clearly, Joost will be the biggest success on the web in 2007. Convergence Culture from Henry Jenkins applied in a creative way.
"The notion of using this type of data for some creative mashups first came up on the Ironic Sans blog, where a Joost fan by the name of David Friedman brainstormed about a feature that he would like to see in the client: The ability to share comments on the programming based on each show’s timeline. Says Friedman: “Imagine watching a show like Heroes once, and then watching it again with comments turned on to see what other people caught that you missed.” Joost is planning "trivia” that pops up at specified timestamps and will timestamped tagging, commenting, annotation, etc.”
So what can these metadata frameworks be used for? Timestamped comments and tags are certainly one interesting possibility. Combine this with FOAF-like social networking structures, and you got yourself a whole new way to explore TV programming.
Imagine a personalized TV channel that only serves you shows your friends are literally talking about. Or think about the way this could transform programming itself. What if the Lost folks didn’t do their next Alternative Reality Game on the web, but in Joost itself, allowing you to collaborate with your friends and collect clues while watching the show? Now that’s what I would call combining the best of TV and the net."
