For a counter example, I read aggregate reports one by one, if at all.  They 
get an automated HTML rendering that makes it easy to see success at a glance, 
and the mail site is small enough that I can afford doing so.  Authentication 
status is visible at a glance too, so I can judge the report's merit.

IMHO, reports SHOULD be authenticated.
