One feature I've wanted to implement for a while is now up and running. Tanktop.tv now tracks what episodes you've watched on BBC iPlayer, ITVPlayer and 4oD and filters them out. This happens automatically when you click on a link to leave tanktop and watch the episode, but you can also set it manually by clicking on a tick or cross next to the episode.
As well as reducing the time it takes you to find something new to watch, I'm looking forward to getting enough data to be able to see what people really like, not just what they think they like. Do I really want to admit to watching nothing but Top Gear, Robin Hood and crazy diet-obsessed car crash TV, never getting around to watching Sky at Night or Horizon?
