Want a good one-man-band podcast that hits the sweet spot? Then put Jim Fear in your blogroll or feed or whatever and watch for him to put out another episode.
You cannot get more fundamental in Being The Culture than seeing one man run his own show. He calls the shots. He records, uploads, and spreads the word as best he can with what he's got. No bullshit, no corporate meddling, no PR people leaning on him to bend this way or that- just Jim, just as he is.
If he can do it, then so can you. Take the very fact that he has a podcast as proof of concept that you too can contribute your bit- and those bits do add up over time as well as in concert with others of similar mind. He's being what he wants to see.
