Wow, this started out as a point of view and turned into a rant ...
If you insist on keeping everything you download, then extra drive space is cheap. I bought a 2TB (2000GB) external drive for 400 bucks. That is in addition to the 600GB already in my computer. Most of the stuff on my computer is large, memory intensive graphics related to work.
As far as podcasts go, I tried keeping them all, then made playlists for everything (MTM Minutes for instance). After about 5 played, they just became background noise. I lost track of what I had listened to. OK, so I bought a notebook and started writing the main points down from each podcast. This takes a little time. However, once written, I remember the material longer and I don’t need a computer to find the lesson again. Most of my MTM podcasts are now noted like this. Handwritten, not digitized. I play something brand new, make notes and finish by reading the notes I have made of other ones. I only need to read them a few times and they are committed to memory. Then an occasional review to keep them fresh. This whole process of reviewing my notes takes less than 20 mins. (I am keeping the SMSM program though). In the end I spend less time with each podcast than I did before and get more out of it.
It is a good organizational routine and works for me, others will think it is whacked. To each their own. Regardless, I spend less time loading my iPOD with “stuff” (because there is less to choose from), get to the workout faster and get it done so that I can still go live life. I stopped being a slave to technology, and found that it is a great tool.
There are some things that I listen to over and over, but not many. Even if I kept everything forever, I still only listen to a few things again. Most of it would just get lost in the clutter anyways.
I save the new podcasts for my daily commutes and listen to them there first, and again in the next day or two to make notes. Then I usually trash them. I now limit my podcasts to what I have the patience to archive this way, and the rest have been unsubscribed. Like food, everything is best in moderation. This includes, but is not limited to: sleep, work, sex and yes ... podcasts. I spent the first 35 years of my life without podcasts, they are not going to dominate my time now.
This won’t work for everyone. I do not have a lot of time to listen to things. My job keeps me moving or on the phone and in front of clients. Podcast time cuts into my personal time, therefore, every minute spent at the computer downloading or organizing is a minute not spent on execise or with my family. I am inherently lazy, and will use any excuse not to work out, work, or get up an get moving.
I beleive I have beat this to death. LOL I must now turn off the computer and go exercise. I am only on Day 2 and I am already procrastinating my workout. You can publicly lynch me later, but first I must workout.
