I'm confused about the premise of this thread. It seems to me that people don't know what a certain photo looks like until they see it. So what does the total number of views have to do with popularity? (They could look at it and think it sucks, but that's still a "view.") Now, if it has a lot of people marking it "favorite" then, yes, it's popular. But the number of views? Isn't that just a result of how long it's been on flickr? Enlighten me.
