Markets dont work when everyone knows what I am THINKING. i.e. If I know with 100% certainty you are going to buy something for 1$ I just bid 1.0001. Same with Google search. If I know with 100% certainty that you rank pages in a certain way, I can game them. Markets only work when all data is available but no all opinions.

Introducing random elements just makes it worse for everyone.

So why was google more effective before? Is this is product of the financial struggle of our society, or do you believe it is an inevitable consequence of a dominant search engine?

It is a lot more effective for me. I usually find what I am looking for in the first few results, there are flights, calculators, wiki pages, etc. So I disagree it has gotten worse.

The task of search has gotten exponentially harder as well. There are billions more website pages, more spam, more sophisticated attacks, more gaming of the system, etc. They could have gone from a 80% relevant result to a 99% relevant result and you perceive at 10% drop in relevancy. It's a hard problem.
