Google Reader is best in its class, in my opinion (although I have dozens of RSS feeds, not hundreds.) Google Books is great and represents a huge amount of effort. I don't know where Blogger came from, but Google has had it for a long time; Chrome is fantastic and getting better fast; Google's machine translation of webpages seems to be getting better constantly. Google App Engine, Google Scholar, Google Voice (acquired recently, though,) Google Code (good until Github ate its lunch in my opinion.)
