What? Strong Towns is not just their "content creation", they ARE local organizations. You might have a chapter in your city. This criticism tells me that you don't know what Strong Towns is, what they do, the actual specific policy guidelines they come up with and push that have real influence on local city planning.

Strong Towns gives actionable proposals all the time, and their main purpose is local organizations to actually do local change. To accuse them of being a content creation scheme that does no organizing tells me that you have not looked into this at all and are making immediate assumptions based on the aesthetics of their content.
