I've not seen news software use that by default, but I do
definately run no atime on my news server.  Even though it's small
adding 100s to 1000s each day and expiring each night make it
really un-neccesary to retain the atimes on those.

I'd say that anything that gets a lot of access to many files,
and there is no modification to those - archival files, web files,
etc - that would be a good reason to turn on atime IMO.

I only use it on user file systems and not on / or /var.
