Recently I read a little article in our local newspaper about someone writing/receiving a postcard since many years - it was considered a very rare thing happening. So I emailed them a little bit … and this article is what they made of it:
It’s in German though … because it’s the local newspaper in Kiel.
I try translation (with www.deepl.com ):
“Old-fashioned - not at all!
For Kielius, the postcard has long been a relic of the past. So he was all the more surprised when he recently found a card in his mailbox. He wrote about it in this space - and assumed, in view of his experience, that the postcard was no longer trendy. But far from it! Because afterwards Kielius learned from a reader that there is even an active postcard community in Kiel. Postcrossing is the name of the hobby that has many followers not only in Kiel, but all over the world. More than 800,000 members from 206 countries have peacefully networked worldwide and send each other postcards - to complete strangers. Almost half a million postcards are sent around the world every month. So Kielius was way off the mark - and vows to do better: he’s now trying out Postcrossing, too. So the next postcard sent from Kiel to Brazil will probably come from Kielius.”

I must have somehow missed the article in the news. Thanks for sharing it 
Moin! 
Well done
