  Yahoo Pipes can create automated lists that you can cut-and-paste 
  into blog posts. My only real complaint is with the HTML markup they 
  create. It doesn't look good when you cut-and-paste it into a WordPress
  blog. This is where Yahoo Pipe Cleaner comes in. It is a Greasemonkey 
  script for Firefox that fixes the Yahoo Pipe output so that it looks 
  nicer when you cut-and-paste it into a WordPress blog.

    * removes any H1, H2, H3, H4, H5, H6 headers
    * dofollows the links (removes rel=nofollow)
    * replaces paragraphs with list elements
    * removes all class/id CSS selectors
    * removes media thumbnails from images
