It's not what I suggest, it's what's happening.
I live in a large densely populated urban area and have done for years and I'd say I'm pretty rooted in my little local geographic cohort, which doesn't include anyone who lives in this street or the next, and I'm completely unaware of what the vast majority of what my neighbours see as community. How about you, could you say there is one community that bonds people together?
We all have the same council, so there's some sort-of pavement politics cohesion (but only some, one lot want to gentrify as fast as possible- see house prices- and some of us don't) but it's nothing like how I grew up in a geographic community where every household had the same landlord, worked for the same employer, bought from the same local shop.... had necessarily shared material interests. That's history and can't be wished back into existence with some sort of conscious community activism (like the grentrifiers round here try to do).
fact is, in some bizarre way, I feel closer to you lot than to anyone who lives immediately close to me, even the ones I've know for 30-odd years, because I have some inkling about what posters are into, what motivates, what matters. And I'd hardly say I'm particularly bonded here (u75) in the way some people are.
