TiVo has been publishing their Season Pass stats for a while now. They list the 25 most recorded shows for the previous week along with Director Wishlist and Actor Wishlist rankings. By doing this TiVo offers insight into what everyone else is watching.
The Buzz site takes the usual list of top recorded shows and breaks it down to present the list of top recorded episodes. And then comes my favorite feature: Top upcoming Recordings. This list offers a peek into the DVR schedules of others around the world. Sort of a social software approach to the DVR.
