Google dominating the world

i am listening to pandora.com internet radio and i am noticing that it already has my facebook linked to my pandora account and i never did that. furthermore i noticed when commenting for the first time on someone's blog i could just say use my google account for it and it knew all sorts of stuff about me. and my google account is connected to pandora, facebook, blogspot, ichat, everything. it is all becoming so uniform and connected on the web. it is really convenient. i just like seeing the progression of online tools even now after i thought things like google could not evolve anymore.
