++ It would be great if you could edit or delete your own comments so that "Everything is editable, just like a wiki." =)

I've tried commenting on one question and at least one answer. Neither worked. I also don't recall seeing any comments on answers or questions anywhere. Hope this gets added soon - it's a feature of StackOverflow that adds a lot to the discussions

After the inappropriate question/s posted today, it's apparent that doctype needs some sort way to flag inappropriate and/or spam questions/comments

This is an interesting idea. Are there other sites doing this? I'd imagine the target audience would really dig this
