I used to listen to a number of podcasts regularly, but I would repeatedly notice that I barely remembered what the key points were. In the end, I cut down my consumption more and more, and only listen to episodes that I specifically find interesting, and only when I have the time and mental resources to really listen to them.
Regarding walking your dog: that's true. Walking around is a good way to retain information. That's explained on Moonwalking With Einstein
As a related issue: I just don't understand the audiobook phenomenon. I'm clearly the outsider here. I enjoy reading words, not having them read to me.
> Upside, audio you can consume while doing other things
which certainly makes sense. While I haven't done so, I could listen to a book while driving, cooking, housecleaning, etc. Reading a book requires me to do nothing else in the mean time.
It does, and I've 'read' 10s of millions of words like this in the past year. I read long-form articles, nonfiction books, and fiction books like this. (The one thing I don't read like this is formatting-intensive PDFs, such as many text books, and that mainly comes down to limitations of my current setup.)
For content on the web I use either firefox's reader mode, which has TTS, or emacs' eww browser with the read-aloud script. For ebooks, I use nov.el and read-aloud. Either allows me to seamlessly switch between visual reading and listening to TTS. This make binge reading easy since I can avoid eye fatigue.
Incidentally, I think a lot of people dismiss TTS after trying it briefly because they underestimate neuroplasticity. Normally sighted people can become very proficient at listening to TTS at high speeds, but for some reason I've seen a lot of people assume only blind people can become accustomed to it. Once you become accustomed to it, the 'robotic' nature of the voice evaporates and it becomes as easy and intuitive as riding a bike.
