Digital photo sharing is nice and everything, but nothing beats a printed memory delivered to your home. Postagram, from the makers of the popular photo sharing Instagram app, makes it easy to send photo postcards from your iPhone or the web.
The Instagram social photo app is pretty neat, and real-world photo sharing via Postagram sounds like a cool idea as well.
Postagrams are thick, high-quality photo postcards that can be delivered anywhere in the world (in the US, it'll take 2-5 business days; internationally, a bit longer). You can add an optional 140 character message and the Instagram photo can be popped out of the postcard by the recipient.
You can create your Postagram from the free iPhone app or the web app. It seems like an ideal app for sending customized vacation postcards or just a short and sweet message — one that your friend or loved one can actually hold and display. And it's just under a buck.
Update 2: Register for an Instagram account to use the web app (thanks computergeny!) — but you'll still need an iOS device to take the pics.
