Is it your belief that in the case of asking a question without a clear answer that the quality of the result isn't relevant? Or that all results are of equally high quality? Do you think that the results on the Google SERP are of the highest quality when you ask these questions?

Google isn’t answering your question. That’s not its job.

Its job is to find websites talking about what you entered as your query. If all people are doing is speculating … that’s all Google will return.

If straight up keyword matching was enough then Google would never have overtaken Alta Vista. Ranking useful high quality information higher is the entire point.

It’s still keyword-based. They just weight the appearance of the keyword in the documents now.

No it isn't. Literally Google's entire initial innovation was a ranking algorithm based on inbound links, weighted by the authority of the linking party. At this point I'm bowing out because you don't even know the basics of the thing you're arguing about.
