Jeff recently blogged about how some dangerous elements are close to useful ones and how they are the same size. He was talking about flaws in GMail interface but the same happens on SO as well. 'link', 'edit' and 'delete' are all on the same line and delete being the larges of them is most dangerous one. Especially considering the fact that mere mortals with less then 10K rep can't undelete they own post once they leave the page, as there's no way to find the post to undelete.
So, Jeff, will you stand behind your ideas and redesign SO according to them?
