Because if a user with 200 friends logs back again after a long period 
of time (long after the cache has expired), it will trigger a cache 
refresh for all of his 200 friends in the same time.

Also, a cache refresh can also be triggered by an external event (i.e. 
someone updating a profile and notifying all his/her friends). In this 
case, the user would have to login and manually refresh the cache 
through a button/link.
