If you’ve been a Flickr member for more than a year, you should think about subscribing to Photojojo’s Photo Time Capsule.
“The Photo Time Capsule digs up your photos on Flickr from a year ago, choosing the ones that are most interesting (most views, comments, and faves), then sends them to you a quick email. I’ve been using it for a while, and it’s amazing how nostalgia-inducing getting a little time capsule every couple weeks has been.” — Amit Gupta, Photojojo
Though only a year ago, the photos highlighted in my first email felt like a real blast from the past. Oh, and if you don’t know Photojojo, check out the archives for much photo make and do goodness.
