Over at Poynter, Amy Gahran asks the question, “How healthy is a blog-only news diet?” That’s her headline on a piece about how Steve Rubel of Micro Persuasion plans to try a test of the blogosphere as a rounded information source.

My reaction - biased of course, since I blog - is that surely a blog-only diet must prove more fulfilling than the TV-only diet consumed by most Americans.

Rubel, my dollar says, will pass just about any current events test you can give him after a week without the mainstream press.
