Popular photos on Flickr

On nearly Web2.0 site you see it. It's not the login field, it's not the advertising. It's the popular links where you get to a site that miraculously shows you the most popular item posted or referred to by the users of this particular site.

Well, one famous exception of this rule is a not completely unknown photo community called Flickr. You might have heard of it. Flickr has something different: They call it "interesting" ... interesting.
