@mordremoth It's noteworthy that a big part of the obscene money and resources is finding good quality content automatically. If you allow some manual intervention - and especially if you crowdsource it like you are suggesting - that part can be much cheaper. For example, any old fool could make a search engine limited to WIkipedia and Stack Overflow. Although the internet is a zillion jiggabytes, I doubt the *useful, searchable, text-based* internet is bigger than a single server rack full of hard drives.
