Hi! You more muck-around-able code motivated me to make three more changes that had been bugging me:

  1. I changed the method of checking for a locked post for one that seemed to be working for a few people that had problems (possibly custom-site-style-related?) with my first version.
  2. I made it fail more gracefully with non-DW posts.
  3. I put in a check to prevent space-time vortices.

Since you put in a github link I decided to actually attempt to learn to use my dusty github account! I hope I did it right, it looks like there's no way to do a pull request for a gist but here is my fork (I think): https://gist.github.com/melannen/ac7d03e0255fdfa6086dae63db705dfe

(something seems to have happened to the indents while I was copy-pasting back and forth that confused the version control, sorry. :/ )

Thank you for the fix to the html-stripping! I wouldn't have known where to start on that one.
