This is great though because things have moved on to the extent that you might now have 1000 people who qualify as neighbours, any number of whom you've never met and don't know.

Totally. Cool stat here -- 80% of the borrows in our first semester occurred between people that had never heard of each other. 12% were acquainted or familiar with the person but not friends. Certainly women can still ask friends to borrow "offline!"

You're able to list off the wardrobes (and availability) for your entire neighborhood?

Do you also have any memories of paying to borrow ? :)
