Like\dislike comments on twich chat.
You can like\dislike comments in live twitch chat and place most popular\unpopular comments at the top\btm.
Make it interactive.
It would help broadcaster\users to read most interesting comments.
I think that if we could like or put +1 on a message in a chat to show to a streamer that the message is interesting, it could be really good
(sorry for my bad english btw)
it could also be used in conjunction with an "ELO" that would favor the likes of the moderators.
