I've noticed that there's no option to 'like' a comment in Off-Topic. It's easy enough to post a comment to say you agree, but multiple posts of the same comment just to say you agree with someone would fill up the page quite easily.
It's a relatively simple idea - Kudos aren't available in Off-Topic. So, can a function be implemented to allow users to 'like' or 'agree' with someone's comment in Off-Topic? The 'likes' won't count towards anything, but they'll just be an indicator of who else agrees with a poster's comment.
