In this internet era, we are all surrounded by google. There are many (high traffic) sites dedicated to Google, either official or unofficial.
From google
Official Google Blog
Google Web Toolkit Blog

NOT from google
Google Operating System :Unofficial news and tips about Google
http://googlemapsmania.blogspot.com - everything about google map.

Just by looking at these high traffic google obsessed sites, it's amazing to see how popular google is. Google indeed has done many good things which benefits our every day life. To name a few:
Google 411 : free 411 service. I tried, and loved it.
Google patent search : offers free PDF download. Are you still using paid service or patiently (painfully) printing image one page each time at USPTO?
We are so used to the free services from Google, I can't help asking will this last forever?

I'll keep updating this list. And feel free to let me know if you find any. By the way, should we start looking at sites dedicated to Facebook?
