If anyone is interested in stamps as more of a casual hobby where you get more joy in seeing a wide variety than a pristine, ordered collection, I highly recommend https://www.postcrossing.com/. It's an international postcard exchange program, most certainly low-tech in this day and age, but I find it immensely satisfying. I buy as many combinations of stamps as I can (the US's international stamp is boring) and love choosing the perfect ones for my postcard's recipient.

List in your profile that you like stamps or even say the type you're interested in. You'll be amazed at some of the ones you'll get from all over the world.
