Makes me wonder if Facebook will ever decide they've pursued engagement far enough and that they have an ethical obligation to actually deliver more value even if it comes at the expense of engagement.
Unless they are implanting electrodes in your pleasure centers or are affecting the GDP in a large measurable way, I'm pretty sure ethics aren't really coming into play. After all, they are providing a useful service.
True that. They've simplified communication for their demographic immensely. I talk to people more on Facebook than I'd be able to in actual conversation, because it's such a nonlinear process.
