I assume you mean being given the option to simply dislike a post. Surely it would be better to give a reason for why you disagree with something thats been said rather than just leaving it in the air.
As this is a very supportive forum on the whole, I fear a "dislike" might make some folk less likely to post thus reducing the chance for amicable discussion and the chance for wider education.
It realy has been nice and friendly here for the last year or so with some lively discussion. Simply "unliking" (should that be disliking) would only creat animosity. Nobody with any sense objects to discussion.
