The NYT have discovered advertising agency blogs, and blogs that write about advertising. In Madison Avenue Ponders the Potential of Web Logs they predict many more to come and blogs as advertising space.
Sadly they don't mention our favorite ad agency blog at the moment TBWAblog from Portugal, but they do mention another one we like, trendspotting Influx insights from Sausalito California and Butler Shine & Stern. The usual mistakes from old media are made, they rarely link and on most typead/blogspot URLs they erroneously add "www" to the front (even though there are none). A+ for effort guys, D for the rest.
