One of our absolute favorite API hacks turned startups from this year is Timehop, the ultimate daily nostalgia kick, which sends you a daily email with your tweets, Twitter photos, Foursquare checkins and your Facebook posts from every day, a year ago.
For the holiday season, the team was extra nice this year and pushed out a new product just in time for Christmas. Its new nostalgia packed product is Pastcards– a web app that pulls in your Foursquare, Facebook and Instagram posts from Christmas seasons’ past and then lets you create shareable postcards.
You can edit the postcard or send it out to loved ones via email, Twitter, Facebook or via URL.
