... There are arguments over just how good Google’s results really are.
Particularly when the results are biased by filtering preferences (for google ads for example) AND when they run on with a bunch of garbage listings with little relationship to the query string.
The big problem imho is absence of any filtering based on accurate, verifiable, valid content. Any idiot can (and does) post garbage and it gets the same treatment as good information. The more ignorant people get access to the internet, the more ignorant garbage gets posted, and the more anyone's search gets cluttered with it.
