Aside from the unintended consequences of casual social events planned on FB, there are serious issues arising from the acknowledged data mining for profit business model of many social media sites. We live in a surveillance culture where governments follow our most trivial activities and create data bases around our behavior. Witness China's plans for tallying "citizenship points" to determine who receives social benefits and who is denied them (this includes access to public transportation among other things). We know from the original FB developers that they knowingly exploited addictive behavior models to entice and retain users with the intent of making money off of their 'voluntary' surrendering of personal information. Social Media can create a "Mob" mentality, and issues can be manipulated to condemn or praise a given person or topic without any substantive factual basis. The cesspit of vile discourse present on Social Media is part of our human nature, but amplified and given a mass audience. Even Planetside's business model embraces FB, and I can't blame them. Google and Youtube glean your information in similar fashion and can be used to create individual and group profiles, but sadly I seem to keep using them. Where this is going is beyond me, but I doubt I'm going to enjoy this Brave New World.
