I just recently fall in love with an awesome online service called Postcrossing, using Postcrossing you can send postcards to people all over the planet. Its really amazing. First off you register for an account on the site. After that you can start sending postcards. After you send your first postcards you have to wait for the person you send it too (the person is selected randomly) to register the card with an ID you had to write on to it upon sending. After that, you will be able to resive postcards too. Its a really great way to get to know different cultures and to learn how people think arround the world. If you want to sign up yourself just click here and it will take you too the signup page.
Here are some postcards that I alreday got. You can find more here:
