> I think the problem with the web as it is now is that it's too easy to discover sites. Both are the same problem: it’s hard to find good sites among the massive amount of clickbait, SEO optimization, and generally low-quality sites. It’s a hard problem too. There are a million users who all want blogs, and a million bloggers who all want viewers. The reality is, if you or I were to start a blog it would probably only be interesting to a few people. So your goal is to get said blog to the right few people, while getting a different blog to a different right few people, etc. a million times.

A niche search engine is a good solution, for niche content you already know about. For discovering new niche content you’d need a really good algorithm (perhaps based on similar niches) or some other system.
