Mostly I agree that Drunkduck works perfectly fine. However, how many of us type out a comment on somebody's page before realising that we've made a mistake, and have had to send another comment?
I think it'd be easier if there were some way for us to edit our comments if we spot a mistake/something missed out. What does everyone else think?
This reminds me of something- there's a news site I go to, Kotaku. They have a fifteen minute edit button. Although that might be a bit too much for DD's coding to do. Preview sounds good.
