1. Do a list results view like Google - you're competing on so many levels that you don't want to challenge standards unless you have massive justifications that you're UX is better. I don't think the tiles are better and even if they were a little better it wouldn't be enough to challenge the paradigm.
2. Can you (or do you) restrict search results that have a high AdBlock/PrivacyBadger score? I've always wanted that so much more than I'm concerned about my privacy vis-a-vis my search engine provider?
