Another benefit for this spot would be a place for collective knowledge…a repository for useful ideas, technology, tools, etc. Things that people find practical and useful. The exact opposite of all the music industry or DIY “gurus” promising to give you the keys to endless success and a career…once you buy their course.
IMO, that makes it a place for people to come for things that will help them along the way, instead of another place online for them to argue about stuff. (I also think moderation will play a large role in that as well).
