Doc Searls is critiquing Business 2.0 magazine for hiding content behind a paid-subscription barrier.

What little you gain in subsriber leverage and sales of old articles by putting your "content" behind a costwall is far more than offset by lost authority. When none of your stuff can be found on the Web — either by search engine crawlers or by the countless writers who are denied the chance to link to your good stuff, you fail to exist in the largest and most vital business environment civilization has ever known. Links are what make the Web a web. Preventing them is the height of folly.
