So officially (or unofficially), SaaS is the next Buzzword in Japan.
"Web 2.0" is still big and nowadays you can see them even on tablet papers saying "Web 2.0 is a new generation that allows you to do everything on Free Home Page." Wow, it sounds like Geocities!
But anyway, in this couple of weeks I haven't had any day not seeing "SaaS" on news sites nor blog posts. They'll keep promoting their products as SaaS, even if they're nothing differnt from plain old "ASP".
