ciao, "Where do you meet new people" mean "Meet a stranger in an unfamiliar place". Unfamiliar Place can be anything. Maybe @ cafe, pub, social networking or other meeting activities. As per me mostly these kinds of stuff happen @ Social Networking :D :)

Actually, the question is rather meaningless. You meet new people everywhere. On the street, in the cafe, at school, you name it. I don't really understand this kind of question, either.

It depends in what occasion and where this question was asked. If you provided more info,it would be easier to give you an accurate explanation of it in its specific context.

As others said, it means where can you go to make new friends? The typical answer is an actual place and not somewhere online (although you could say that if you wanted to). I have heard people say they join a church, they take a class, they take up a sport or hobby, or they do volunteer work.

Where do you meet new people= where do you meet people who are not in your circle of friends and colleagues. You can meet them at italki, a pub, nightclub , dating site, activity club etc
