Who are these people?
On Ask.com there are people that I've noticed around. They always give very long answers, often leave links to websites and answer tons of questions in a day. They're very helpful, don't get me wrong, but are they actual people or computer programs or what? They never comment and they often answers the questions that you'd think nobody knew the answer too. I'm not sure if I'm explaining this well but if you know what I'm talking about, please explain.
