Search is broken
Every day Google searches become less useful to me. Search has created a system where those vying for presence must sacrifice quality for popularity. Some search engines are better than others, but that is like saying some cars are more efficient than others, they are still fundamentally all designed the same.
The internet is like a city, there is a giant 20-lane superhighway running straight through the middle. The city sprawls out forever and even with a map it becomes difficult to find what you are looking for. Instead you pull over for a pit stop and end up watching videos in the YouTube district. Domain specific search helps in that it creates smaller highways, but often it simply feels easier to take the superhighway.

Instead I think we need to move towards hyper-localized internet structures where you search and wander around your own network/community of people. You can bump into someone you know on a small street, The internet should facilitate chance encounters
