Here's my "fix the internet" idea: build a search engine that is itself ad-free, and searches over only the ad-free segment of the web. More options: allow users to exclude sites with ads, sites with ecommerce, sites with tracking, or simply allow users to build and share lists of sites to exclude. Rationale: the unmonetized or under-monetized web was awesome, a lot of it still exists under the radar now, and it would be good to reify it as a tangible thing. Bonus 1: competitors probably won't copy your features. Bonus 2: spam won't be a big problem, as most of it contains ads.
