I see plenty of results from Google about this string, from multiple sources and multiple types (video, news and classic links). Unclear about that deterioration.
Right, but Google doesn't show everyone the same results. The earlier poster clearly didn't get a very good search result. If google search is bad for some people or in some cases, it should be a concern for everyone because you would never know when you are getting that poor result.
It basically does show everyone the same results. There's some session-based reranking and ads are heavily personalized, but there's basically no personalization in regular search.
