Polish Tourism and Sightseeing Society is promoting tourism and sightseeing, and one of the means of that is granting badges for various achievements, such as walking above 250 km on tourist routes, participating in 5 orienteering contests, visiting one of UNESCO memorials etc.
Well, you all participate in StackExchange sites, so I think I don't have to explain the rationale behind badges ;)
I wonder if something like that is functioning in Western Europe, especially in Germany.
