Comment (by kencu):

 IMHO - people who want to set up an older, no longer current system to
 install wordpress on for their daughter's blog (for example), keep it
 behind a firewall, and serve up the site on a shared port through their
 router -- don't mind if that system is not state of the art in the very
 very very latest mysql patches.

 but that's me. I don't have any systems that are fully exposed to the open
 internet.
