I think in future google will get Generic_top-level_domain http://en.wikipedia.org/wiki/Generic_top-level_domain like "goo" or just "g" to provide services like foo.goo foo.g maps.g books.g etc etc. :))

imagine www.pring.g ... even without www ;)

And maybe another couple of decades later, we can omit the "goo" extension... it will simply have become default ;)

blogsearch
booksearch
etc.

If you type blogsearch [Enter] in the FF address bar, you'll get to Google's (immature, not interesting, nobody knows about it) Blog Search service.

Yeah, Firefox uses "Im Feeling Lucky" when you type stuff in the address bar. Or , at least the first Google result.
