Quora Hub – Online communities? What are they? Well I’m not too sure. One thing I can tell you is that when I hear those words I usually think of chat rooms. I am sure you know that if you go online one of the things you can do is go into the chat rooms. In fact, one of the first things I did when I first went to America Online was go into a chat room. I remember my friends telling me how much fun it was. I wondered what was so fun about it.
