Collect Post Cards From All Over Without Traveling

I was doing some random surfing of the Internet last night and came across something very kewl for the armchair traveler: Postcrossing.

Postcrossing lets registeres users exchange postcards from random places all over the world. We're talking about the traditional old fashioned paper postcards, not electronic postcards too, so this is a great way for the armchair traveler to gather up a collection of post cards from around the world for their travel scrapbook.

I'm even considering joining to get post cards from places that I could then investigate for the Travel Journal.
