I argue that stale content does make the customer service phone ring. People
get upset when they use out-of-date information. Expires headers are useful
in some cases, but not in most. Most current practices don't allow
caches to be as agressive as they should be to be most efficient (ie, IMS
requests are too common).
But none of this is a cache hardware/software problem - it's lack of
protocols and standards (aka - poor design).
