I'm seeing this as well. Also, the headings that appear to be intended as cuts have links to your reading page (which I'm sure isn't what you intended) and trascendenza's post. If you copied a lot of that post from your reading page into the RTE, that could be where the extraneous code comes from (the RTE is, apparently, legacy code of unusual opacity). Do you mind if I look at the page source and see if I can debug it? (View Page Source is a Firefox function which just shows the HTML for the rendered page, not what you see in the editor.)
