When someone asked my friend "where are you from?", he always replied "I'm from the internet".
This might seem like a weird answer, but I think it was spot on. When people ask this question, they usually want to know about their culture. Internet always had its own culture. Netiquette, netart and early memes. This answer actually was better than saying the name of the country.
Now there is no single internet culture. Can there be one for nostrians?
