Techdirt pointed out an interesting retrospective by Scott Rosenberg, former managing editor of Salon.com, about their experiments with paywalls and how repercussions can last a lot longer than some might expect. "More important, by this point the public was, understandably, thoroughly confused about how to get to read Salon content. It took many years for our traffic to begin to grow again. Paywalls are psychological as much as navigational, and it's a lot easier to put them up than to take them down. Once web users get it in their head that your site is 'closed' to them, if you ever change your mind and want them to come back, it's extremely difficult to get that word out."
