Yes, and that is a great thing. When journalism was the old school "I get a few bits of info and use it to decorate a short article with my uninformed opinion about random topics I have nothing to do with", it was worse. Each time I had an insider knowledge of the topic, I was horrified by how biased, approximate, reductive, or plain wrong journalism was.

I also have direct reports (my wife) of journalists asking questions in the streets to many people until they got the answer they were looking for. I bet it is common practice: you are not only told to write a piece about X, you are also implicitly told what to write and you just bend your material, data or street interview or whatnot, in the direction that will get the more emotional reaction from the reader.

Disc: I'm talking about French journalism here, maybe US journalism or Eskimo journalism is magically much better, I don't know.

For non-anonymous answers, they ask the writer before publishing. I was just published on there, and got a Quora message asking for my permission. Not sure how they handle anonymous answers.

Yes, it's called "aggregation."
