I think its always better to give a post in agreeing or disagreeing with a reply because it adds to discussion rather then everyone just 'liking or thumbs up' someone's reply. Thumbs down option I just am not a fan of, on every single forum I have been on that used this did get abused one way or another. Doesn't mean necessarily that would happen here, my point is that it has a bad history for people misusing it, and its like a ticking time bomb really, takes one person to misuse and then things get nuts. As for thumbs up, that is not bad in comparison but again I prefer the idea of actually getting your point across in a thoughtful post rather then some button. Just because other forums do it doesn't mean we have to, my honest opinion.
