I don't think year-based versions (like 2011.0 for the first 2011 
release, or maybe 2011.5 for May 2011) are pretty, but I'll make an 
argument for them anyway: it makes it easier to figure out when hardware 
ought to be supported.

So if I buy a 2014-model laptop and the coffee-making button doesn't 
work, and my favorite distro is running the 2013 kernel, then I know I 
shouldn't expect to it to work.  (Graphics drivers are probably a more 
realistic example.)

Also, when someone in my lab installs <insert ancient enterprise distro 
here> on a box that's running software I wrote that needs to support 
modern high-speed peripherals, then I can say "What?  You seriously 
expect this stuff to work on Linux 2007?  Let's install a slightly less 
stable distro from at least 2010."  This sounds a lot less nerdy than 
"What?  You seriously expect this stuff to work on Linux 2.6.27?  Let's 
install a slightly less stable distro that uses at least 2.6.36."
