Excellent note. It all comes down to the battle of *ownership* in my mind. Who actually owns the online entity, whether it's Ning networks or your Twitter and Facebook accounts? Is it the person, or does it always remain the platform? (something else to write about?)
For example, look at sites like
Assetize. If a person has put in the work to build up these entities, shouldn't they have all rights to monetize them or move them as they please? I think they should, but obviously these platforms disagree: they'd like to continue to claim full ownership and reserve all rights.
