(Why leave a review? Podcasts depend heavily on the reviews listeners leave. iTunes uses them to determine whether to bring them to the attention of potential listeners. Under the right conditions, iTunes will feature them in their New and Noteworthy lists for a category. How does that work? No one knows. But reviews clearly help through some algorithm locked away in the Apple vaults guarded by the spectre of the ineffable Steve Jobs himself. )
