im always wondering how to quantify the self reinforcing aspects of popular videos. also it seems like score decay based on time should be completely controlled by the user
As I understand it, the formula is designed to keep a trending video around on their list for roughly a day. It would be interesting so see a list which optimised for showing videos (of any age) with accelerating views, and had a stronger decay over time, so you could see what is trending right now, but it might be heavily biased by the very recent uploads from popular creators.
