I am beyond concerned about Facebook graph search… I have been tempted to leave Facebook numerous times already for similar corporate invasion of social media, but always was forced back because no one else feels like migrating.
I understand that corporations need information for advertising, but this is getting a bit ridiculous. This information needs to come from more voluntary sources like surveys or product registration, as the majority of Facebook users are less than likely to read the fine print before agreeing to update after update of their privacy policies.
I feel like GNU or FSF should sponsor a “free” social network, which could be funded by donations and contribution, much like GNU/Linux operating systems, where our expression and interaction will not be exploited for personal gain, or that very least be honest about doing so. Perhaps an incarnation of IRC with a GUI more oriented toward less experienced users?
