Facebook is one of those companies that's captured the imagination of everyone. Marketers, technologists, privacy advocates and "regular people" have all talked about, written about and been on TV talking about the company.
The things they've written about have ebbed and flowed over time. Sometimes they were talking about the unethical beginnings of the platform. Sometimes they were talking about how it completely ate the lunch of the previous network, MySpace. Other times there were conversations about privacy or about making it easier to communicate with old friends or do business.
