Just an idea here. Didn't know where I could send suggestions so sorry if theres already an email dedicated to that but anyways.. I think it would be agood idea to put a "like" button on comments, like many other sites have. youtube, facebook, ect. Maybe even a way where you can write a small comment within a comment. Ya know something that doesn't take too much space but allows for a little expression. Smily face, "haha", ect. Just a thought. I think it would be a popular tool.
