Google Earth blog – not officially affiliated with Google. I love this blog because it provides Google Earth KMZ files of buildings and other models to load in Google Earth. It also informs you of GE updates and upcoming new features.

Lifehacker – a productivity blog where I spend an inordinate amount of my day. Lots of computer / internet tips on how to be more productive. Quite often, the user comments are more educational and amusing than the actual Lifehacker article! Several MakeUseOf articles have been mentioned on Lifehacker.
