Sadly, postcards are not as popular anymore as they once were, which is why in many places they are increasingly hard to find. Postcrossing has been trying to revive the culture of sending postcards, with remarkable success, and there are communities of collectors across the globe.
The use of postcards to send greetings to friends and family has sharply declined in recent times, mainly due to the rise of email and social media. Postcards take days, weeks, or even months to reach, and buying and posting them requires both time and money. Yet, there is magic in sending handwritten postcards that cannot be found in the digital world. Postcards travel large distances and pass many eyes before they reach their intended recipients and at the same time are more intimate and personal than an email or social media post. Kept in a safe place, a postcard is a physical reminder that someone thought of you, and cared enough to make the effort of sending it. It is a memory that lasts.
