You made me not only feel old, but you made me too curious about this game so I had to install it. I really hate you guys.
Caught a four pokemon already. Since my office is in a small medieval town the pokestops and arenas are in very very picturesque locations. I love it. I am totally amazed even by the small amount of information about all the stops. It looks like they really datamined the global photolibrary, since one pokestop right next to my office is located in a very small alley and was represented in the game via a photo of a memorial plaque for a local author. I never paid attention to that plaque, which is kind of sad that this app made me aware of it.
I think that Pokemon Go is the geocaching of the digital age and generation.
