Apartment Building Social Networks

Smartmobs has a discussion on 'Apartment Building Social Networks' that engages in the debate elsewhere on the web:

Fact of the matter, Apartment Building Social Networks like LifeAt.com are also good for local search marketing - because they create contextually relevant local real estate content to advertise on. In fact, I predicted the rise of local social networks will call for most local businesses, that still don’t have websites, will want to once they have places nearby to advertise on.
