"To roam Flickr is to wander through crooked teeth, local politics, nesting osprey, birth, spaghetti, divorce and every other aspect of existence."

And wonderfully interesting it is, too. I've spent ages, on and off, refreshing http://www.flickr.com/photos just watching the world go by.

Note also http://www.flickrvision.com/ is also quite good for watching the world go by, in a slightly different way.
