Added punctuation.
  Updated comment discussion.
  Updated to use e-comments rather than inline code.

  The external comment system was written for this site,
 but has been tidied up and released separately now.

  If users wish to clone this code then they'll be talking
 to the production comment-site, rather than a local instance
 anyway - as the comment-server endpoint is set to http://comments.../
 rather than "http://localhost...".

  On that basis storing an outdated copy of the comment-server
 is not doing anybody anything useful.
  Avoid fast-spiders.
  Optimizations for page-rendering.

  * Inline the CSS, to avoid a round-trip.
  * Move the comment-loading to the foot of the page.
