Integrating social networks into search engines just sounds like something straight out of a web 2.0 idea generator. I don't see how this will be useful at all.

Integrating social networks into search engines just sounds like something straight out of a web 2.0 idea generator. I don't see how this will be useful at all. I'm gonna make a guess that the kind of highly general searches this would be good for (like band names used in the article) is only a tiny portion of most actual searches. Even then, people might rather just ask their friends if they want this kind of information. Another thing, the vast majority of links shared by my friends are hardly informative, maybe weird, funny, awesome, etc., but few people post stuff on Facebook like they would on HN. Without context, they will only clutter up the search.
