There is only one podcast that I have continually followed over the past couple of years, and that is LDS Voices. The podcast is basically a massive collection of talks from General Authorities, auxiliary leaders, and noteworthy LDS scholars/professors/motivational speakers. Each day a new talk is put up (audio only). It covers everything from General Conference and BYU Devotionals/Education Week to firesides and random lectures/seminars. The talks range from 7 minutes (short Gen. Conf. talks) to over an hour (Hugh Nibley/Truman Madsen lectures) in length. They are almost always highly uplifting and I have greatly come to enjoy my morning drive to work/school when I get the chance to just listen to the talks and let the Spirit come into my life to start the day.
My recommendation (if one feels so inclined to listen also) is to search for "ldsvoices podcast" (or something similar) in the search bar in the iTunes Store. Then you can set it up to automatically download onto your compy everyday and listen to it on your iPod on the go. However, if you spend a lot of time at home with a compy nearby, then they also have a website which allows one to access these talks (audio only) for free.
I may start commenting on things I find interesting from these talks if I find myself in the mood, but there will be no structure to it. It will be all higgeldy-piggeldy, running amok with these things. That is all I can promise for now.
Here is a link to the site: LDS Voices. Enjoy.
