Stop trying to improve it to death like yahoo groups , answers and all the other forum that are now defunct because of "improvments"s
Advertisers wont pay Yahoo if there are no viewers to click articles. The comment/reaction section is a massive piece of Yahoo's users. Much more than the minority that is complaining about something that is optional th o look at. So what if some people think its bias, or theres some conspiracy if they get thumbs down because their post sucks or if they believe the authors are terrible or if they are too stupid to realize why their comment was deleted or not posted.
