One, it's important have several different common spaces that are used in different ways.

Two, it's about setting specific guidelines about how those spaces are used.

Three, it's about selecting for people who tend to be inclusive rather than exclusive / cliquey.

So far so good.

That's great to hear. It's hard for me to over emphasize how extremely interested I am in the social and physical architecture of human thriving. I'll be watching Common with wrapped interest.

The only thing I watch with wrapped interest are Christmas presents =P

I hate to be exclusionary but wouldn't you think that if you were so introverted that you had a hard time sharing a space with other people then maybe you shouldn't live in a shared situation like this?

Even if everyone in the house is an extrovert compared to the wider world, someone is still going to be the most introverted person in the house. And the most charismatic and extroverted person in the house is going to relatively dominate the common space.

It's a recipe for conflict, and if they don't have a formal way to precess that conflict, there's going to be either bloody noses or hurt feeling.
