I’ve tried a number of UX podcasts. Some of them are too chatty, some are more about the presenter, and some are just not very good. This one is very good. It’s practical, the presenters know what they’re talking about, but are open to learning, and they have good interviews.
Jared Spool’s podcast. Low frequency.
Professionally done. O’Reilly also have other podcasts that might be of interest. This is low frequency also. I find their website quite confusing, rather ironically.
