Trejdify was a link-submit site similar to Hacker News. It was a community of readers who needed fewer but better business news. The problem it solved was that there's too much information and every single person doesn't have time to go through the information on their own.
"News is to the mind what sugar is to the body. News is easy to digest. The media feeds us small bites of trivial matter, tidbits that don't really concern our lives and don't require thinking. That's why we experience almost no saturation. Unlike reading books and long magazine articles (which require thinking), we can swallow limitless quantities of news flashes, which are bright-coloured candies for the mind." - Rolf Dobelli
But a community can filter these news flashes and find the real articles! The reason is that the group is better at finding out what's good and what's not - compared with the individual. It has been shown in the book Yes! that approaches and outcomes of groups who co-operate in seeking a solution are not just better than the average member working alone, but are even better than the group's best problem solver working alone.
