This has been on my mind for some time now, I really think it's a good idea, the "like and dislike" won't really count for anything its just a kind of check as to how reasonable people find your opinions.
I don't see any reasonable reason for the forum to introduce such a feature man, where we already have the merit system and the ability to reply to a post or comment stating our agreement or disagreement, a like and dislike feature will be or is utterly useless.
This is not to talk about the fact that such a feature may likely end up discouraging or lowering posts engagements, in the sense that where a user should reply to a post stating their agreement or disagreement and reason behind their choice, they will choose to rather like or dislike the post and move on to the next one, this will do nothing but create confusion over time, and I guess you know the type of confusion I am talking about.
