Most of the most consequential changes to the reddit feeds a few years ago I was involved in or directly came up with. The most visible was probably the one that started putting discussion-heavy posts on the front page (things like legaladvice, amitheasshole, askreddit, unpopularopinion, etc). It’s weird to think about the resulting butterfly effects that are completely beyond my knowledge and comprehension.
It's crazy how things have changed. Reddit is now heading in the opposite direction. It's a shame, because I think that your approach was the better one.
