I feel like a cool thing for Highlighter would be podcast transcripts. One can post quotes are still relevant from older episodes. Hopefully we get the prism thing going, and...

-part goes to the person making the post,

-part goes to the pleb that took it upon himself to transcribe the podcast

-part goes to the podcast (of course) but for this section, perhaps you can tap into the shows podcast 2.0 split, so that everyone associated with making the show gets their cut.
