“Everyone is famous for 15 people.”
Alas, there is the truth of almost all media. The sad truth for almost anyone “famous” is that it is small and fleeting stuff.
Having heard all the damning of “mainstream media” folks, I’d just like you to know that about 15 people will recognize you once you have a big success with podcasting, blogging or a television show. That’s just how it is; there’s nothing particularly new about the “fame” associated with these emerging media, except that a whole new crop of people will learn what it is like to be poorly paid and gratified on the rare occasion someone actually recognizes you.
