Have you ever started a podcast?

I'm an avid podcast listener. It's probably my most consumed media. I would guess I've been listening for maybe 15 years? Maybe more?? Every so often I wonder what it would be like to actually start a podcast. Seems the boat has probably sailed for an amateur so I understand if I ever did it, it would just be because I wanted to and I would have no expectations to successfully monetize it. Just out of curiosity, have any of you actually tried to create a podcast? How'd it go? How long did you last? Maybe you're still going? What was the gist of it? Did you do it with other people?
