Dave Winer thinks we should own our data, including movie ratings:
This is a long-told tale here on Scripting News. The classic example are the movie rating data held in silos by sites like Netflix and Yahoo Movies.
But whose data is it??
Seems it belongs to the users and they should be able to take it where they want. Sure Yahoo is providing a recommendation engine, that's nice (and thanks), but they also get to use my data for their own purposes. Seems like a fair trade. And I'm a paying customer of Netflix. They just lowered the price but I'd much rather have gotten a dividend in the form of being able to use my own data.
Think of the mashups that would be possible.
Wouldn't it be great to link up Match.com with movie ratings to find dates that like the same movies?
Some of my Netflix Friends have rated thousands of movies, written scores of reviews, and have hundreds of movies in their queue. This data has a lot of value to these people, and there should be a way for customers to backup or transfer this information into other services. While it doesn't make sense for Netflix or Blockbuster to do this, it's a good opportunity for a third-party developer.
I'm also surprised Blockbuster hasn't figured out how to import a Netflix queue yet.
