Now imagine if this vacuum could be filled by competitors that right now don't have a chance to go against a de facto monopoly on social networking? Wouldn't it be lovely to see all the new products that could take over all these domains without the clutter of being Facebook: event scheduling/marketing, marketplaces of used goods, neighbours' community groups and so on? Why should I feel sad that one major company isn't dominating all these spaces at the same time?
