I knew they had plans to takeover the world / the internet, and now with their IPO money they can do it pretty quickly.
Everyone's revenues are slowly going to drop as Google and other first point-of-entry sites control where their surfers go; to your sites/services, or to theirs.
Mapquest will die with Google Maps, all other free services for VoIP will die / not be able to compete with Google once they release that... and the list goes on.. Google Hosting soon I'm sure, Google Web Design, Google Amazon-store, Google DVD rental services, etc. etc. etc..
What else could they take over?
