John Lam - "Unlike NetFlix or Amazon—though they protect user privacy, ultimately they serve private interests—Movielens serves as a collaborative filtering platform for the Groups Lens research team at the University of Minnesota. Because they've accepted National Science Foundation grants for a large portion of their research, they must also abide by its participant research guidelines. In addition, they also must adhere to University of Minnesota Board of Regents participant research guidelines." (link to entry)
