*I think a like/dislike would be a lazy option to not join in the conversation? Mind you I can see the appeal as some prefer to read threads and not post.*
I agree. We already get so many comments from people who say that they never join in certain threads because people might disagree with them. This inevitably leads to 'the same voices' being heard on such threads, which is a shame, as a broader range of views would be more interesting for all concerned. A 'like/agree' button would make it worse, I think, as it would appear to give a voice to those who aren't prepared to contribute to the thread. Discussion needs contributions or it dies.
I don't think having an up or down arrow would stop people contributing to the thread. If they have something to say they will say it. But sometimes you just want to say 'I agree' or 'I don't agree' without adding anything further.
