Whoa, this is a very interesting idea. Think how this “fits” with a flat-lining economy. “Sharing” is a DIY kind of activity, where “entertainment” in our time, often means becoming a consumer and paying for something:

Stated simply, 7 million people in the U.S. are contributing content online through six or more activities (uploading photos, publishing blogs, posting ratings/reviews, etc.). These heavies are also connecting with 248 people in a typical week, on average. Needless to say, the news they choose to spread can change the marketplace overnight with such scale that companies must tune in and be in a position to react quickly and decisively.
