Using Social Media to create the next generation company

I'm interested in how social media can or will change the way business ideas are created, developed and commercialized. Is it possible that the next generation business will be built with social media applications and through social media networks? I think so, but there needs to be thought behind how to organize a business such that the strengths of social media networks and applications are used to the businesses advantage. Are facebook, linkedin, wikis, squidoos, google apps, ning, xing, salesforce.com pieces that can be used to develop the nextgen company? A nextgen company that uses social media to network people to create knowledge, ideas, awareness, demand, products and profit?
