I don't find this very useful. My friends often like things that I don't like. They're not my friends because they like the bands or movies or web sites that I do. Recommendations from my friends carry no more weight than they would from anyone else. The only difference between a friend and a stranger is that I might engage a friend in a conversation with specific questions about something they've used or seen that I haven't, but the value of that conversation comes from the detail of the exchange and targeted or objective questions I'd ask, it's not expressible as a boolean like/+1 or a 1-10 rating.
