Why Netflix Never Implemented The Algorithm That Won The Netflix $1 Million Challenge | Techdirt:
"The viewing data obviously makes a huge difference, but I also find it interesting that there's a clear distinction in the kinds of recommendations people that work if people are going to "watch now" vs. "watch in the future." I think this is an issue that Netflix probably has faced on the DVD side for years: when people rent a movie that won't arrive for a few days, they're making a bet on what they want at some future point. And, people tend to have a more... optimistic viewpoint of their future selves. That is, they may be willing to rent, say, an "artsy" movie that won't show up for a few days, feeling that they'll be in the mood to watch it a few days (weeks?) in the future, knowing they're not in the mood immediately. But when the choice is immediate, they deal with their present selves, and that choice can be quite different."
