Rachel makes an excellent point here about feed change frequency.
Seems like it'd be straightforward to implement a backoff strategy based on how frequently the feed content changed into most readers. For a regular, periodic fetch, if the content has proven it doesn't update frequently, just back off the period for that endpoint.
