It is my goal to receive one postcard from every country in the world. It's tricky for various reasons; Somalia currently has no postal service and there are similar problems with a few other countries, but it's a long-term challenge anyway. I'll just collect what I can find.
I'm also interested in cards from remote spots, like Petropavlovsk-Kamchatsky, Ushuaia or the Isles of Silly. Just for the heck of it.
If you'd like to help out, there is a form on the bottom right of the main site. Naturally, I'll send a card to you as well!
There will be a map/list of what I've covered soon.
