Oodi is more an experiment in creating a social, communal meeting space than a library. I think there's a terrible need for such social spaces in modern society with very few places where you can meet people and where you don't need to consume to hang out somewhere; this especially in countries with climates that make it difficult to hang out in streets and market places.
What's also special is that this is a beautiful building, instead of the derelict buildings such social projects get usually shoved away in.
And, it's welcoming to babies and children.
