Interestingly, that's the "trick" behind a lot of the seemingly magic skill of geo guessers. The best players have played so much, that they now "see" things that a regular person wouldn't even consider to look for, like the camera quality, what year the car was from, and so they narrow down the possible countries by those aspects, before even looking at the "picture".
Not worth it for me. Don’t care if we together are more productive; I couldn’t care less. I care more about my eye sight, and sitting routine.
I cannot talk to someone else for an hour without feeling exhausted and needing a long break afterwards.
Talking to someone else while programming? It's revving up my brain into the red zone. Sometimes the adrenaline boost does its job but I do pay the price.
