Better Facebook sharing
If I post the link to a movie page in Facebook, the preview only shows "Movielens", not the title and no image. I know that chasing after Facebook changes is difficult, but maybe there are some small changes that make for a better sharing.

Great feedback, thanks for sharing. I’ll add this to our to-do list.

Currently the movie pages are restricted to signed-in users. Part of making it easier to share movielens pages involves creating a version of the site that not-logged-in users can see. Thus, fixing facebook sharing is actually part of a larger issue that we'd like to address sometime soon.
