Facebook is 21st-century cigarettes. Thousands of brilliant scientists and engineers testing and optimizing their product to be as addictive as possible. No concern for the effects on their users or on society. The only concern is making money. Just like with cigarettes, at first it was cool, then it became mainstream, then the dangers became better known, then the CEO was ordered to appear before Congress and gave a lot of misleading and empty responses, now it's used primarily by laggards and poorly-educated demographics. I'll be glad to see them go. Because one day they will go.
