It's shorter to type. That can't be true of an awful lot of names though, even for most travel and jobs sites this new extension could be pretty pointless.
My own take on the proliferation of new domain extensions is that it's a license for registrars to print money, more than a reaction to actual demand. Adding new ones doesn't so much open up the opportunity for other people to use already-registered domains, because of all the branding and trademark issues. It just compels certain sites to register more variations in order to protect themselves.
