More on sub-text

  I see the value in sub-text but I can't shake this feeling it has more potential in some application that nobody has thought of yet.
  I noticed something new about it today (This isn't the breakthough. It likely won't be I who thinks up the breakthrough!) It's in Dave's The Value of Working Together, posted this morning, his first post that uses sub-text since I tried it out and tried to think what I would use it for.
  Only the first paragraph of the sub-text section shows up in the feed. For those lingering few publishers who don't want to give away the full text in its RSS, this would be a way to save little bits of content for people who visit the site directly.
    I'm not a full-out full-text feed advocate. In rare circumstances I think you should hold things back. I work for a membership organization where two of the couple-dozen information products produced by my unit consistently rank as the number one and number two benefits of membership. So are we going to give it all away to people who have not paid their dollar per year per employee?
  For all I know Dave didn't intend to hold back any part of his post from the feed.
