Pre Search is an interesting idea... But their products seems to be a DuckDuckGo skin with an ERC-20 altcoin attached to it 🙄
Reputation staking on the validity of a web-article or search result is on the one hand very interesting, but on the other hand, will lead to people being able to "buy" a higher search result without having better content, just deeper pockets (like add-words combined with SEO work today).
Just use You.com or Duckduckgo.com...
