When first reading (or not actually reading) this post, I thought "What's the task? Go to the local bar and drink a beer, then enter the museum and scan a QR code to prove, you are there..."
But then, I realized what it's actually about: Collecting information to show others in OpenStreetMap, like "does the bus stop have a trash bin? Or what kind of asphalt does the street have?"
I think, I'll try this out tomorrow. Thanks!
