This guy talks about the "profitability" of Facebook. Why should Facebook be making a profit? If they charged a fee to belong to their site, that would be a legitimate profit. They don't charge you anything. Instead, they require you to reveal your personal information, and the information of your friends, family, enemies, associates, co-workers, etc. and they SELL this information without your knowledge and without your consent (since you didn't realize what you were agreeing to).
Believe me.. Facebook's days are numbered. They are a mountain of fraud and corruption. Even if they could managed to legally dodge their fraud and corruption, once their userbase becomes cognizant of what is going on, they were dump facebook like Abe and Trump dumping food into the koi fish pond.
