From the guidelines - and I think a much better way of adding commentary & changing headlines:

  Don't abuse the text field in the submission form to add
  commentary to links. The text field is for starting
  discussions. If you're submitting a link, put it in the url
  field. If you want to add initial commentary on the link,
  write a blog post about it and submit that instead.
