The impact to podcast quality

Just read an interesting article about how a regular contributor to Podshow is leaving, because the burden of producing three shows a week was impacting the quality of the podcast.

It's been my sneaking suspicion for a number of months, now, that this will prove to be the case more and more over time, and when more and more people find out just how much work is involved in producing quality podcasts on a regular basis, there will naturally be a "culling effect" that weeds out the hobbyists and those who are really serious about fulfilling their lifelong, formerly-thwarted dreams of broadcasting their own content on their own terms, on their own time.
