Resonating Questions for a Global Public Sphere

This week I found it really helpful when we discussed our reactions to the 2x2 by Jackson and the 2x2 Jason created. After class, I have been thinking a lot about how social media can serve as a global public forum on many different levels. In regards to social media, how would a company that only interacts domestically fit in to the 2x2 when it uses social media to interact domestically? Does that mean that the company creates a global public sphere if it only physically interacts on the domestic level put attempts to create a global public sphere through the use of technology? What about news sources that also use social media in an attempt to facilitate a global public sphere but filter their news to only appeal to a specific domestic level? Does an opportunity for a global public sphere, even if there is only domestic interaction in that sphere, still count as a global public sphere? With other types of global public spheres, do these questions have similar answers? What about the issues that Mike discussed in his post this week? How would they relate?

These questions are operating under the assumption that social media and technology can create a global public sphere by transcending territorial boundaries and giving the opportunity for people from all over the world to discuss issues.
