I think it's a love/hate feature, but I'd really welcome some of those of agree/like buttons to react to posts. In some of our quieter threads where people are reading but don't have anything to contribute, it would be nice for a poster see their post get some reaction button presses to know they're not talking to themself.
Yeah, I've seen this on some other forums and I think it's really cool to have those buttons for Agree/Awesome/LOL or whatever. Especially as you say on here where people don't necessarily always have a response but can give some feedback and/or encouragement to the person who posted.
A recent example of this I've seen is the Marvel Heroes forum
where they even go the extra step of having little achievements/badges for getting 100 Agrees and such. I think that sort of thing can potentially really help encourage positive discussions
