## Finalize RSS support (COMPLETED 2024-11)
Marginalia has experimental RSS preview support for a few domains. This works well and
it should be extended to all domains. It would also be interesting to offer search of the
RSS data itself, or use the RSS set to feed a special live index that updates faster than the
main dataset.
