I've been exchanging postcards on Postcrossing (<a href="https://www.postcrossing.com/" rel="nofollow">https://www.postcrossing.com/</a>) for years, it's very fun! I've even been to Postcrossing meetups, where several members gather to sign postcards so you send them to people.<p>In Postcrossing you put your address, and then you can request a random one. You put an ID, so when the recipient receives it, they register that number and you get a postcard from a random member.
Postcards, while travelling, are one of the very few instances when I write by hand, these days.
I started about 20 years ago, I most usually only write the address and a smiley — the old school analogue medium is most of the message (that I take the time to pick a postcard, which then has to travel physically to reach the distance to its target).
They're everywhere. But if you're short on time, buying the postcard is often easier than getting stamps and dropping it in a postbox.<p>One petty complaint - generally across the world, stamp design has nosedived. Compared to old postage stamps, they have terrible typography and gaudy colours. I've generally been disappointed when buying stamps to put on postcards. Old stamps were truly works of art.
A year ago I started sending postcards to my 91 year old father because he has difficulties with modern forms of communication. They do still exist but you have to search for them.
A friend just sent me one from Minnesota!
