What if - someone started an offline social network with physical footprint?
Start off with a coffee shop(or other) - tailored to a certain persuasion.
Less cops needed (it's not a liquor joint and the cops are likely there already).
Let's say that some number of folks may not have a physical outlet their concerns/beliefs/passions - just electronic.
Shills will never prosper in that environment - unless it;s two of them - which will be shown the door.
