At times, there's nothing more amusing than watching a blogger in the middle of a meltdown. Barry Ritholz, the CEO of stock-research firm Fusion IQ, has apparently been seized by panic over an interesting, but unthreatening, development: Big media companies getting into the business of selling ads for blogs. They've already built up an expensive ad sales force, and often find it difficult to grow traffic on their websites faster than their salespeople can sell it. A natural solution: Approach blogs covering similar topics and offer to sell ads on their sites, sharing the revenue. The Washington Post was one of the first to do so, and now, apparently, Reuters is getting into the game. The part that has Ritholz alarmed, though, is a requirement that the blogs "assign" their traffic to the larger company for purposes of getting counted by Nielsen/NetRatings and ComScore Media Metrix, the two largest Web-traffic research firms. Why does Ritholz find this so alarming — and why is he utterly wrong?

The social-networks phenomenon is influencing the most unlikely candidates. Nielsen, the company behind TV ratings and other media data, is working on a network called HeyNielsen that will measure product "buzz." [PaidContent]
