Charles Warner at Media Curmudgeon thinks that the amount of blog spam he's getting from GM and Chrysler may be a sign of desperation. Warner, who recently added comment registration and turned off trackback pings, reports that a good bit of the spam is from GM and Chrysler.

In a little leap of thinking, he took a look at BusinessWeek's most recent list of top 100 Global Brands and noticed that neither U.S. carmarker was to be found (although DaimlerChrysler's Mercedes brand was on the list).
