well if I have a system where inconsistent data is OK, I just let the normal cache expiration time logic handle that. Turning down expiration times to a few minutes, even 30 seconds, can still take lots of load off of particular "hot" objects that might be fetched multiple times quickly (such as from a series of AJAX requests) while making it unlikely that large inconsistencies will show up on the screen.
