I read through the suggestion box and haven't seen anyone recomend this yet: Is it possilbe to add a "like" button for posts and comments? Maybe something that keeps count of them like on Youtube. I think it would be a great tool to let people know we appreciate their comments.
I know we have the thumbs up icon we can paste in our comments but its hard to "like" someones elses comment when the thread is already 30 comments deep.
(Feel free to thumbs up if this is a feature you'd like to see)
