Doc Searles has been discussing branding and blogging;
"Ever notice that the companies that tolerate, and even encourage, blogging... also suck at branding?"
This makes sense. In order to have a good brand, a brand that everyone recognises, branding must be strict. It must be rigid. It must be enforced. It must be anal. You can't have people running around willy-nilly using it, slapping a logo up here and there. Funny how a company who has an image of being creative and breaking moulds such as Apple will have to be complete facists about to branding. There has to be a trade off somewhere.
