The most recent episode of This Week in Media, #115 has some interesting comments about Twitter's impact on Brand marketing. TWIM is a great show if you want to understand the developing space of new media. Comments starting at about 47 minutes made me realize how important it is for marketers to stay on top of every kind of marketing, especially social networking apps like Twitter.
