I've been working on a link aggregator. https://matrix.gvid.tv What makes it interesting is that it has some anti-echo chamber technology, or soft echo-chambers. Every user is in a 3 dimensional space. Every post is sorted by its distance to you, score, and age. When you upvote something you move towards it and it moves towards you. When you downvote something it moves away from you, plus a little bit in an extra dimension that moves it away from everyone. That means you can see content that you like without any hard edges for echo chambers. This also means that if you want /funny/ to be pozed like a typical redditor it can be. But people who want to post edgy memes to /funny/ won't have their memes immediately downvoted. They instead will be seen mostly by people who like that user's content. And if it is very very good then it will get enough votes that the pozed users will get to see it.
