We can get the most relevant answers on top if the algorithm decays voting power for historical votes. Fresh votes will keep relevant answers at the top.

- dragontamer 7y agoThere's no way to automatically know if an answer from 4 years ago is still relevant today. Maybe it is, maybe it isn't. Trying to tie an algorithm to "age decay" is the wrong solution, because it will decay too quickly for some questions, but not quickly enough for other questions.
- stevenwliao 7y agoIt's softer than the original proposal: instead of archiving an answer (reducing vote weight to 0) at an arbitrary time, we do it gradually at an arbitrary rate.
