Perhaps it’s just me, but maybe there are others in my boat: I simply don’t get anything out of listening to podcasts. If I’m doing something else (driving, coding, whatever), I concentrate on that, and so what’s said goes in one ear and out the other. I could make the time to sit down and just listen, but a half an hour here, a half an hour there is a fairly big tax on my time, especially when compared to reading, which for me is far faster than listening, and easier to do a few minutes here, a few there.
I realize that it costs money to get the transcripts done, so not everyone’s going to want to make that happen, and I’m cool with that. I just think yours happens to be worthwhile and I’d love to read it!
