Going from creepy to completely unethical, Facebook ran a psychology experiment on almost 700,000 users. I’ve had a tenuous relationship with the service over the years, and now, I’m deleting my account for good. You can still find me here, on Twitter, and in real life. Looking at Facebook from a cost-benefit perspective, there was little in the benefit column. I “like” all of your baby pictures and will see you around.
Don't panic, there is still a free lecture-capture solution for everyone.
