I think we need an alternative search engine based on community vetting.

I.e. you submit your url to the search engine but it isn't present in all search results until a certain number of real people will say it's meaningful and useful. You can do that by only showing it first in 1% of search results and ask people to rate it.

You don't have to index 10 billion websites, you just have to index 1 million of useful websites.
