Another forum that i use allows you to 'like', 'dislike' or 'laugh' at posts as well as being able to reply.
I really like this format as it allows you to interact with post/comments without having to post a full reply (esp. good if someone else has already said what you wanted to post).
This doesn't seem to cut down on the number of replies on the other forum just allows another way to interact.
Would you enjoy this feature, is this something MN have ever thought of implementing ?
