Even more Interesting, individual cities (at least ones in AK and HI) have similar URLs as well, including ones that did not previously have a "hostname" site.
This will help to eventually eliminate people whining about random cities and towns not having "their own" craigslist "page" - if they implement this widely, EVERY city of any significance will automatically have its own "page"
I am very much in favor of this change.. Kudos to whatever programmer is making this happen.
