Carl Bialik, a WSJ reporter, wrote two related articles in the last few days on the topic of determing the value of PR. One was an article for the WSJ and other for his blog. I commented on both, taking the pro side of the need for PR valuation -- and as one of the few voices mentioning that value can be determined.
Note: You may need to be a subscriber for at least the article.
