Exactly, unless she expects every reader to configure the polling interval for her blog this isn't a good solution. I would highly recommend she sets `Cache-Control: max-age=3600` or something similar. That is at least a method that can automatically be applied. Sure, right now most readers just use fixed intervals, but further support for this is a standard that can be pushed slowly. Plus some readers probably use HTTP libraries that would automatically cache the response so some clients will accidentally have support.
