Three of the blogs I've followed for a long time are: Kevin Drum, Life on a Colorado Farm, and Northview Dairy.
They're in California, Colorado and New York; Kevin's a liberal, the two farm women are more conservative (though they don't mention politics much). Kevin seems to be urban, the other two rural. So you assume they don't have much in common?
Wrong. All three of them like photography and photography of hummingbirds, as you can see by the links above. Kevin, however, has the advantage of a new and expensive camera, but all three appreciate the same thing.
