Need for Serendipity engines

Wandering around the web is like living in a world in which every doorway is actually one of those science fiction devices which deposit you in a completely different part of the world when you walk through them. - Douglas Adams

• We revisit handful of webpages.
• We need serendipity engines - like search engines.
  • Wikipedia, Zettelkasten, StumbleUpon etc are serendipity engines.
• Aggregators have overpowered serendipity engines because we find comfort in Confirmation bias.
• Our imagination is limited by our experiences. Since imagination leads to queries, we need to expose ourselves to varied experiences to push our imagination. See Infinite Buffet
