Here's a new Change This Manifesto on Open Source marketing... Worth a read. James Cherkoff is a Director of Collaborate Marketing, an independent consultancy in London. I'm not sure that conveniently bundling all new forms of marketing - guerrilla, social networking, community etc... under the banner of Open Source isn't a bit of a disservice to both them and Open Source. What James does do is provide a useful construct though for rethinking marketing. Thanks to Steve for pointing to this one.
