You're raising an interesting point, but you're coming close to saying that communities are bad, and in my experience they don't have to be. Even ones based around a product.

Near where I used to live in the Valley, there was a real-world club for enthusiasts of a particular weird antique car. Not toxic, just eccentric. They just liked getting together and drinking in a nearby pub and showing off how they'd restored this or that aspect of the car.

I think our goals should be to replicate that kind of success.

I think the other posters in this thread have it right, that the reason why we usually can't is because our metrics are all about selling audiences to advertisers.
