I don’t think counting there vote less is useful. Low quality signal that is plentiful is very often better than sparse higher quality signal. My past experience is working on recommendation systems at tiktok/snap. Having a lot of weak signal from casual users is extremely helpful for power users. Recommendations are often based on large amount of basic engagement data. I think a large aspect to TikTok’s system being considered strong at recommendation is because Ux is designed for very frequent simple signals. I can also say working at companies like that generally any system changes require an ab test and long running back test. I’ve generally seen companies move from 5 star to simpler like/dislike system and those changes would have been ab tested and found that user experience is overall better. I don’t know for specific systems whether overall better was across all users or some users.
