StoryCorps, of course, is the series of interviews/dialogues between ordinary folks that runs on public radio and elsewhere, getting archived at the Library of Congress. I just learned they have an app, making the series accessible to anyone. Beautifully designed, easy to use, free. I plan to take advantage if it.
The app triggered an additional form, the self-interview or audio selfie. I'll begin there.
Maybe start a series at Russellville.
