While we're at it, some kind of "Does not interrupt the speaker" tag would be great. It absolutely drives me nuts, listening to stuff like This American Life or Radio Lab, where the person being interviewed never gets more than half a sentence out before the narrator overdubs themselves correcting or summarizing what the speaker is trying to say.

I find it incredibly obnoxious. You brought this person on to tell a story: let them tell their story, goddammit!
