But why shouldn't a headline be link. I've been doing some research and I can't find much on the subject. And there is nothing that says don't do it. Yes what goes between hx tags should be a headline or its equivalent but that doesn't mean it cannot be a link. Header elements are use to create structure within a document. A heading or subheading may after an intro lead to a nother page where there is more information.

Would you advocate not linking blog titles in an archive? In situation where you have a heading that you want to link, I would suggest linking it. The alternative woule be to have 'Read more...' text or something similiar alongside the header which is bad practice. Link text should be descriptive. So a h2 that is a link with text saying "An article on cheese" is of more value than a link saying "Read more..", in my opinion. As I said originally though, if it isn't necessary then don't do it and I can't think of many cases when it would be necessary but I can't sse how it would be damaging.
