I have downloaded all of the podcasts, and listen to them in my car. I find it much more soothing than getting mad at NPR.

I really enjoy them. I find something I can gain from in almost all of them, even when they do not have much directly to do with what I like to brew.

There is only one little tweak I’d like to hear. When you talk about something coming up “this fall” or “next spring” there is no point of reference. It would be helpful if you would mention the original posting date at some time in the podcast, say right at the beginning, and maybe also at the end. So if a book you refer to is already out, I won’t be waiting til “next spring” to look for it.

Other than that very minor thing, I really love them. Most of them are worth listening to many times.
