When you are running the Pirate Bay the internet is real life, and it also is when you have a business, but when you are on an MMORPG or Twitter it is real life to a much lesser degree. How can we distinguish between them? Well, the majority of relationships made on MMORPGs or Twitter go nowhere outside the platform, and the things that people discuss on them also tend to not involve anything that will still be there when the person logs off. That creates a pocket universe (with a few exceptions, I think some people have met their spouses on MMORPGs) unrelated to the real one. Operating Pirate Bay, or even talking about Linux kernel drivers on IRC, doesn't meet that criteria of being separate from real life.
plenty of "real life" places also fail this test though. most work/school relationships don't "go anywhere" outside of that bubble. what fraction of people you hung out with in school or ate lunch with at previous jobs do you still actually talk to? how much of the code you wrote still runs in production?
Hopefully the money you make at work bleeds out into real life. :-) Also, I think a lot of people stay in touch with their college friends.
Besides that, the recognition that your school or office is a bubble universe in certain ways sounds like an important one. You sound like you're attempting to refute the idea but I think you're making a good point. Someone who implicitly thought their highschool was the whole universe would be in bad shape when they graduated.
