On a public-facing server I tend to make /var a separate partition, and 
sometimes I'll go as far as making /var/log a separate partition, since 
I have been burned before by log file growth.  It does depend upon the 
use case; for my Scalix servers the /var/opt/scalix dir was always on a 
separate filesystem, and even today on an e-mail server I would likely 
put /var/spool/mail on a separate partition or logical volume.  Nothing 
like an e-mail DoS to take a server down when / or /var fills up.....

And I love LVM for the most part, since it allows you to do 
'repartitioning' without really repartitioning.  Yeah, it adds a layer 
of complexity, but flexibility does come at a price, and LVM is very 
flexible.  Although now that most of my storage is on EMC SAN it is 
easier to resize what the OS considers to be whole disks, and so I will 
put different filesystems not just on different partitions but on 
different LUNs and manage with the EMC Unisphere tools.
