What is a self-interview? Well, it's when you ask yourself a question then immediately answer it. Are they occurring more now than before? Listening to people on TV news shows and NPR seems to show that more are doing it now.
Why would people do this? Because it makes it sound as if they're answering a question that has been asked -- even if the answer they're giving wasn't actually in response to the actual interviewer.
Can we stop this now? I sure hope so.
