I still think that the internet can make people who live near each other meet and socialize. I don't understand why no site like this is being created, and why facebook has become so alienating instead of becoming a site that encourage exclusivity between friends. People are really adopting the jetset attitude of social circles, always excluding the more people they can because they think it will improve their social life.
I have thought so long and hard about my isolation, I also had the idea of: * building new types of apartments where people live together, instead of individual apartment that make you feel you are in a prison cell, unable to see your neighbor. People eat together, but they still have their bedrooms and private space. Basically you make life collective instead of individual. You reduce costs, so it's another incentive for people with low income. * Renting large apartments with many bedrooms and organizing life with people inside of it. * organizing regular meals for 10 people at a time, to improve food quality and make people eat together.
I'm really tempted to create this kind of real life, "open" social website where you can do things with people based on proximity and maps. There are a million things people can do in the context of a sharing economy. It would be targeted towards isolated people so that they can find each others.
