Thanks for your comment, @jbn.

Because they are a neglected community here.

This is an inherent problem of the floodgates of the Internet. The Internet has always relied on curators. Yahoo! initially was a directory of sites. There was DMOZ also as an influential player around century turn. Then there are the manual curators, people like Jason Kottke, John Gruber (Daring Fireball), Andy Baio (waxy.org), and many more.

When search engines became the more prevalent Curators, we also saw initiatives like Digg and Reddit come to the fore, at heart popular content discovery platforms. Upvoting platforms.

All of these have constantly been gamified. It took Google years to improve its search results and get rid of low quality, or even spam, in it. Even to this day Google is constantly being gamified. SEO is a very lucrative business, and an expensive one at that for its customers.
