How Bout renting a big house and allowing everyone to have their own room?

I think it then would be important that we don't bother eachother, which is a common problem with blocks of flats.

That can easily be done by college students.  College campuses often have houses for rent within walking distance.

That depends one the individual apartment complex you're in and the types of people there.  (e.g. I'm rarely bothered in my place.)

I would imagine that there would be quite a few participants who just want to be left alone.  But there would also be some who want to be social and need some like-minded people to socialize with (albeit with the alternate skill set I mentioned earlier).  For that reason, it would have to be near places where they can meet.  (e.g. a coffee shop within walking distance)

I'd move to an aspietown given half a chance.  Forming a community around similarities isn't segregation.  Segregation happens when people are ostracized.  Coming together to form a community would be a choice.

I can see it being a good thing if all the practicalities of setting up and maintaining such a place can be agreed upon.

What if there aren't enough jobs for Aspies in the area?

Couple of problems:

First, the possibility of this turning into a ghetto for us; getting everyone of one type to live in one area of the city has not worked out well historically.

Second, gentrification. Enclaves of people looking for a place to live tend to choose low-income areas because those areas have cheap houses. If the people who move in manage to get decent job opportunities or bring middle-class style establishments with them to service them, they raise property values and rents and push out other people. If you're gonna do this, you have to find a way to make sure that any prosperity that comes to the neighborhood benefits everyone there and doesn't just push all the poor out.

Some company might actually be attracted to implement their office in such neighbourhood. Computer one would probably be the first. But accounting would probably follow real close behind.
