Hi Brenda,
First and most importantly, thanks for creating your podcasts. They are excellent.
I think your Podcast on "How to stay safe while hiking alone" is very well done. I've hiked the entire 2200 mile AT and my hiking kit/plans have all of the essentials that you recommend. The only exception is a "Space Blanket". I carry a tent, sleeping bag, puffy jacket and waterproof shell. Thus, I don't typically pack a Space Blanket.
Your other tips on lost/found, compass and map are right on target.
Bottom line - I love your podcasts and thanks for creating them.
