I was introduced to a fabulous site, Blogger Play. It just runs a slideshow of all the photos that are currently being uploaded to Blogger. If you find one that piques your interest, you can click on it to be taken to the blog it's posted on. The only problem I've had is basically every picture I've clicked on has been from a non-english site. Doesn't really do much for me. Apparently we english speaking folks don't have any interesting pictures to share.
