Sometimes I see a post and think, yeah, a like button would be good, but the site works better without one.
Right now, the internet is probably half bots. Forcing someone to actually respond to a comment instead of doing an automatic "like" cuts down on the bots.
I've also watched several message board type sites get destroyed when a specific group gets together and mass downvotes every comment until a user gets banned.
Like buttons and emojis allow people to scatter gun instead of forcing them to actually think and respond.
It’s not like we are all egalitarian and stuff here on FR.
A “Dislike” button isn’t required just because there is a “Like” button.
