You can count the number of people in the US who are making a living by podcasting on one hand. Podcasting is a great adjunct to a business, but as far as living from it, few people are willing to make the sacrifice it takes to transition the "valley of death" (no money) to get to the profitable side. Anyone who does it for a living is doing it as a FULL time job. This "four hour work week" nonsense that at least one slimy podcasting "consultant" advocates is pure folly.
