Oh, I agree.  Personally, I update the kernels on my boxes every time.  
There's a reason Linus & Co. put out fixes, and unlike "other dev teams", 
it's not to hurt us.  It's to help us.

If someone wants to avoid doing reboots, then this way--bringind down the 
kernel update anyway, but scheduling your reboots, say, monthly--is, I think, 
a good compromise between Rob's desire for uptime, while still getting all 
your bug fixes.  If something does come in on the updates announcements 
mailing list, then you can do "emergency" maintenance (read: a 
non-regular-interval reboot at night).
