I don't often check my Flickr photo stats, but I happened to the other week and found a massive spike in the number of views. Normally I get around 100-200 views a day, but on that particular day I got 569,829. My theory is that they came from this post on Viralnova about money trees. I reckon that somehow embedding the pictures on that web page caused the view count to go up. It's interesting that as well as the two money tree pictures the ones near it in the photo stream also got a lot of views. I couldn't find anyone else reporting that they've had a similar big jump, so I put this post out there in case someone knows just why the pageviews did go up.
