This works pretty well. I tried it with this guidance prompt:
    You are both pelicans who work as data
    journalist at a pelican news service.
    Discuss this from the perspective of
    pelican data journalists, being sure
    to inject as many pelican related
    anecdotes as possible
You can listen to the 7m40s resulting MP4 here: https://simonwillison.net/2024/Oct/17/notebooklm-pelicans/
Example snippets:
    You ever find yourself wading through
    mountains of data trying to pluck out
    the juicy bits? It's like hunting for
    a single shrimp in a whole kelp forest,
    am I right?
    The future of data journalism is
    looking brighter than a school of
    silversides reflecting the morning sun.
    Until next time, keep those wings
    spread, those eyes sharp, and those
    minds open. There's a whole ocean
    of data out there just waiting to be
    explored. replies(6):
