Stumbled upon a new tool today: Flickr Scout by flagrantdisregard.com. Basically it will show you if any of your photos have ever been in the the top 500 interesting photos for the day and gives you some stats about those that have. So far, only my “what’s in your bag” photo has ever hit the list.
There are some other strange little Flickr doo-dads at fd’s Flickr Toys page. I haven’t played around with them too much, but some of them look like fun.
