What with all the social networking going around on the internet these days…

1) I want to recommend a movie to my parents. Why doesn’t Netflix have a “recommend” button?

2) Why haven’t I been given the option to “friend” my parents (or anyone else) on Netflix in the first place?

3) Netflix seems to have a solid algorithm for recommending new movies for me based on my viewing history. Given (2), why can’t I view my parents’ recommendations? Or better, a list of suggestions for movies we’d both like?
