That's a good question. I currently have 2. Mysterious Universe and Higher Side. MU I usually cancel for a while and then catch up closer to the end of the season. Eventually, I will probably stop subscribing to them altogether. I've notified them a couple of times when they got names or dates completely wrong and they were less than gracious when responding. I think they are finding some interesting material in the Theosophic Library that coincidentally is right near their current studio. But other than that there is a lot of repetition on that show. They have quit editing and are basically releasing the show as recorded, which hasn't really made a huge quality difference. But my feeling is that they are riding the gravy train for as long as it lasts. I really dislike it when Aaron goes on about buying expensive electronics and furniture. But I've been supporting them for many years, and they have become something that I look forward to listening to, as much for their silly commentary as anything else.
Greg I have supported periodically because I think his podcast is fairly unique. It's way out in left field most of the time, but I like to listen to that stuff because it helps me feel out the boundaries of credibility and belief. Greg clearly isn't living the high life on his profits. Even so, I will probably cancel that subscription soon. I keep a fairly tight budget and I already have Netflix, Hulu and Prime subs for the family. Plus I get an Major League Baseball sub every year on Father's Day when it goes on half price. I like the way things are moving with media--allowing us to choose a la carte what we want and when. I doubt many services will be must haves on a permanent basis. Hulu, for instance became a lot less attractive when it peeled off the Criterion Collection. I honestly watch very little media these days compared to a couple of years back, but my "kids" are still heavy consumers.
The reason why I won't subscribe to Gordon's podcast is probably more involved. I don't really view Gordon as a particularly deep river. He seems likable enough, and he is a good talker. He has a good memory for things and he synthesizes pretty well. I've bought and read all his books and to be honest, I haven't been impressed. Add that to the fact that I am moving into a phase in my life where I view the occult less as an interesting project to tinker with than as something to question very deeply whether I should really involve myself at all. It may be temporary, but "The Siren Call of Hungry Ghosts" destroyed a metaphysics that for me had become quite pat and comfortable. I'm back again to the idea that there is a great mystery, but that I have very little idea what might be truthful about anything man has written or thought about that mystery. I'm honestly trying to move away from thinking about abstractions and more towards doing things with my hands that I enjoy, mainly woodworking and repairing stuff--maintaining things, small engines, buildings, retaining walls.
