The largest issue with search is that we learned about it when the web was young, when the universe was 'complete' - the entire web was searchable!

If you're going to build something, don't build on land someone else already owns. You want your own land, your own domain, your own sovereignty. Trouble is, so much of the choice land - the land where all the people are - is already owned by someone else: By Google, Facebook, Twitter, LinkedIn, Yahoo, and Apple (in apps, anyway).
Google Now is one of those products that to many users doesn't seem like a product at all.
