The problem with marketing is not interruption. Nor is it false claims or agency/client compromise. All those things and more are deficiencies in the practice of marketing but they're not the root problem.
No the real problem with marketing is that it all too often follows the creation of the product/service and thereby is reduced to promotion. It is bad promotion that is the bane of most anti-marketers. Not marketing itself.
All those conference ideas about branded utility, shared interests and authenticity are good ones, but they'd be much better if they weren't add-ons.
