Re 1: I'm a human, not just a worker. I don't need to go out for beers every week after work, but knowing my coworkers as humans is a nice bit of human contact... if they're not jerks or too messed up. (Otherwise, knowing my coworkers personally is a bit of human contact, but it's not nice...) Re 3: This works... for maybe the first 10 or 15 years. After that, switching too often can be a red flag, limiting your ability to land the better jobs.
