Google could go a long way toward improving their search results by just flat out banning the worst offenders, but that is where their size limits their options. If Google banned Pinterest they would likely face an immediate anti-competitive complaint. Google is so big—has such a large market share—that they have to operate pseudo-governmentally, by creating and managing neutral rule sets (or at least what appear to be). It feels to me like there are search opportunities somewhere between Google (the everything engine) and individual site searches (which usually suck). I often get my best results out of Google by using their “site:” operator to target the few sites I know are likely to be useful.
