one of the main reasons why I work at Facebook (4 years now) is because I genuinely like the product, and I know lots of people who it brings legitimate value to. Obviously we have made lots of mistakes and bad decisions -- nobody can deny that -- but I think we get a hard time on HN because the core demographic group here (young affluent american males) is one who sees basically no benefit to the product, so they're weighing those harms against nothing. If you talk to some people who genuinely use and love the product (who do exist!), you'll get a different perspective.
