My biggest gripe with the comment system is that you can't leave comments anonymously. If you like the pic, it's no big deal to leave your name, but God forbid you leave some constructive criticism. I appreciate when people take the time to actually tell me how they think a piece could be improved. However, I've nearly come to the point where I won't even leave any more comments unless they are COMPLETELY positive. If I even hint that something could be improved, I get into a big IM argument nearly every time. It's not even worth fooling with anymore. I've found that I've gotten much more truthful and useful feedback at deviantart.com than I do here...
