I listen to the show while out jogging, so I listen to four or five shows in one burst every other day. I'm not yet advanced enough to listen to the intermediate shows, but I've been working my way through the Beginner lessons, Survival Phrases, Culture Classes, and Newbie lessons. I've got through all the Survival Phrases and Culture Classes; I'm up to date with the Newbie lessons, so I listen to those on the day of or day after release; and Beginner lessons I'm just up to the start of series 2.
I actually tend to listen to the show in order to back up what I've learnt by teaching myself using textbooks. But I'm hoping, some time this year, to find the time to push on and improve my Japanese enough to start listening to the intermediate lessons.
Being that I'm a "Newbie", and I've been on this road for about a month now, I listen t the Newbie, Beginner, and Survival Phrases about 10 hours a day at work and during my bus commute. I sit in front of a computer all day so it works good for me and then I reinforce by studying the PDF's at night and on the weekends. And I listen to each lesson over and over again until I can remember it. At times when I can't "really" pay attention though I do like to just listen forward as far as I can up the ladder because it can't hurt, and I really really looooove Naomi Sensei's accent when she speaks English.

I listen to almost every lesson, but I skip the 'newbies' Instead, I add some EnglishPod and ArabicPod, and occasionally one of the other languages. At the moment, I download about once a fortnight, adding some older lessons and other podcasts and I then I listen to them on a daily basis, while walking the dog, driving my car, and so on (so much for Zen...).
It's really helping my Japanese "to the next level"
I listen to almost every one except the newbies, but not necessarily every day, sometimes I catch up on a few days worth later on. I'm at the intermediate level, but the beginner ones often have things I haven't seen in textbooks.
I listen to almost everything (not all of the newbie lessons) and I actually keep an archive of these lessons on my ipod and use an "intelligent" playlist to "relisten" to lessons after about 6 months.
(the bus I take to work takes quite long, so this is a good way to pass the time)
I used to listen every day. But, somehow, I felt I hadn't really learned everything. I was skimming the surface. So I went back to Beginner Lessons. I'm on Beginner Lesson #132 now. I use the Learning Center to review the kanji, content, grammar and vocabulary. I practice the line-by-line audio and record my voice (that's helping me a whole lot! ) Then I take the quizzes. So, it's really helping me to do that. Once in awhile I listen to the current lessons, but I really need to get the basics down. It's a little frustrating because I really want to learn everything at once!
