I recommend storing the feed content once it's retrieved. It's just
polite. Many feeds provide a TTL value (that's the RSS terminology)
that tells you how often they may update the sight. If it's 45, for
example, don't hit their server more often than that. It spares their
server some load. You can also use the last modified and etag
response headers to determine whether anything has actually changed
and only retrieve the feed if there is new data.
