I agree mostly with what is said in the article, but I don't know anything about the site they promote in the end and actually I doubt that this site can be the best place for collecting feedback about your product for example. Can't we use Google for that purpose much more effectively? But I'm far from saying that it can't be helpful at all for anyone. For example I like the idea of the "wisdom of the crowd". Indeed you can gather creative people in one place and make them work on ideas which can be really helpful for some projects.

Overall I think that community is extremely important for any crypto project. Only it should be a real community of people devoted to the project, not a bunch of bounty hunters with throwaway accounts.
