On information pages such as the how to answer page, headers should have an id, so that reviewers can easily target them in links. For example, if an answer is posted with only a link as content, we should be able to link them to stackoverflow.com/questions/how-to-answer#link-context.
As a side note: it would also be nice if the system could detect if a post only contains a link, and either prevent the answer from being posted, or show a warning message.
