I take a different view from TheFonz. I worry about who is already my listener and keeping them happy. If I owned a store that sold business suits, I'd worry about keeping my customers and building my customer base from people who buy business suits. I would not be worried about the guy who does not need nor buy business suits. In other words the small micro streamer does not even register on my radar. Most all of these formats will only attract a handful of people, none of which would listen to my station that is charged with gaining as many listeners as I can get.
Another thing critics of radio people fail to remember: it is not about us. It is us doing the job we have been hired to do. By saying it is us to blame for a format, too many commercials, playing the same old songs and such is akin to saying the cook at McDonald's is responsible for the quality of meat purchased for hamburgers by McDonald's when the cook merely cooks the meat patty. In other words, we are doing a job dictated by those who employ us and the decisions we make are based on achieving the goals the employer wants.
And might I add, there is a place for that micro internet broadcaster that serves a handful of listeners. The best venue seems to be streaming. Radio cannot economically do such a format. I call myself a music explorer, always have been, but I'm in radio and that is my job. On my own time, it is fun to hear music I may not have heard before but I must agree that with each unfamiliar song, there is a big risk I will go to the next stream. In fact, it is so difficult to find many on the same page when you play new or unfamiliar material. I compare it to Christianity. I worked a Christian station and thumbed through a book of denominations in North America. It was like a White Pages directory for Los Angeles or New York City...so many, many groups with their own set of standards that don't mix with any other group entirely. I suppose the varied backgrounds create the human condition that means few are entirely on the same page on every aspect. These microcasters are fine tuned for their groups yet radio tries to find the common denominators that allow as many differing groups to come together to make a crowd so it can be economically viable.
