Have you checked out Photojojo's Time Capsule? Every 6 months (or you can change the time of your time capsule) they'll email you with your most interesting set of photos from the past. I had it set for 3 months, and I was in Canada 3 months ago and I forgot what a pretty photo this was. It was taken at Cupcake Conspiracy, one of the best tasting cupcakes I've had (sorry, Sprinkles).
Sign up for your Photojojo Time Capsule HERE. The only requirement is you have a flickr account.
