Should I use the picture-in-the-picture feature?

A nice answer for a question about using picture-in-picture in video records.

The picture-in-the-picture feature is where a small video of you appears in the lower part of the screen as you are narrating something on the screen. Some people say that this helps to “humanize” the screencast. To my mind, it’s one more thing to worry about, and unless you are George Clooney or Angelina Jolie, it probably doesn’t add much to the screencast.
