How often do you send a real postcard these days? Almost never already, right? Facebook is now testing a feature that allows you to turn your Facebook photos into physical postcards that can be sent to your friends. And just like a traditional postcard, the photo will be displayed on the front of the card and you can type a personalized message to your friend on the back.

Postcards will allow you to type in your friend’s address if you know it, or ask him or her for their physical address is you don’t.

The service is powered by Sincerely, the company behind Postagram, an app that allows you to send Instagram photos as postcards using an app on your phone for $.99.

The service is only available to a select number of Facebook users for now. Sounds like fun! Especially when you're traveling. Postcards are a nice touch after all. What do you think of them?
