The internet is an incomprehensibly massive entity that is made up of people that come from every different walk of life. This huge variety of people provides an equally huge pool of knowledge that can be gathered. There is one pool in particular that comes to mind, and this pool is of course Reddit, and it's fitting motto, "The front page of the internet."
Reddit's amazing success does not just come from the sheer amount of knowledge, however, I believe it is equally attributed to the democratic system Reddit has put in place. This system is based upon the iconic 'up-vote' and 'down-vote' actions that can be taken upon any post, anywhere on the site. The idea is simple, the more up-votes, the higher the post appears on the site, and vice-versa. This is a very effective way of automatically organizing the content of the site for the best, most interesting posts, curated by humans, for humans.
This might not seem like a huge innovation, but this model doesn't just make reading blogs bearable, it has been adopted into virtually every system on the internet. From amazon ratings, to the facebook like button, micro-democracy has had a profound affect on how we experience the internet, which products we buy, movies we see, music we listen to, or information we trust, without an algorithm.
This system has given us a way to effectively sort through all of garbage in order to find the diamond in the rough. Whether you're trying to learn how to code, build a car engine, buy that perfect television, or just looking for the funniest cat picture, we can do it all instantly. Now you can find out that the soldering iron you want breaks after a month, before you buy it and we have the vast amount of humans pooling their knowledge to thank.
