Time Capsule: An Intimate Service That You'll Like
Photos are valuable because they're personal. In this age of digital cameras, you likely have as many photos as rabbits have offspring.
It's thus difficult to reminisce because a) you probably have thousands of photos, and b) they're out of sight on a hard drive or in the cloud somewhere, and thus out of mind.
Time Capsule remedies both the too-many-photos and out-of-mind problems by hooking into Flickr and emailing you some of the most interesting pictures you uploaded to Flickr a year ago.
TC also lets you leave a message for yourself that it will send to you in a year.
Time Capsule makes you feel really good because you're reminded of old memories when you see your year-old photographs. It's an intensely intimate and useful service that is too rare these days. Any time you can help your customers feel good when they use your service, you're sure to have a winner. In the first TC email I got, I was reminded of a fantastic trip I took to Napa last year and it brought up warm memories of drinking great wine, eating great food, and playing cards with great friends.
If you have a Flickr account, sign up for Time Capsule here -- I don't think you'll be disappointed.
