I find use for G+ due to the same higher intellect density that my circles generate on it.
If Google were really interested in integrating their crawling search with social search, they'd provide a "share this search with your circles" feature on the google search page, together with some descriptive text that you add like in a normal G+ post .. so people in my circles can respond with results that they think are relevant/related/tangential/interesting/whatever.
