Movielens is non-commercial product. Its emerged and maintained as a product of Grouplens Research group. They may not have put effort to integrate with some obvious SSO but its definitely worth a try.

P.S. I am biased because I have worked in Grouplens research lab for a short time and I have loved interacting with all the students and professors there.

Yes, I'm aware of the background, but surely if they want people to use it, they should take the best route to achieving that? Or if it's a learning experience, learn part of the reality about getting people to use a service?

Otherwise, how many of us look over the page and then walk away?
