Can Community Media Learn from Religious Broadcasters?

The Educational Media Foundation owns and/or operates 245 "christian" radio stations in the USA under brands such as "K-Love" and others. Registered as a not-for-profit educational organization, it enjoys tax-free status, while taking in $160 million in donations annually from individuals and businesses.

So what can community broadcasters learn for this phenomenon? That people who believe in your mission will pay to support it, and that building relationships with those supporters is accomplished using effective management. What do you think - is this model informative for community broadcasters?
