I'm not the previous commenter but here my take on it. > Invasion of privacy, profiling and tracking are big issues in my opinion and I would be curious to know why you don't think they are worth mentioning. The thing is that they can do it. It's like saying people shouldn't listen to other people conversation in public. Sure it's "wrong" to do it, but you do know it may and will happen. The web is public, I'm not the only one that can your comment here and that's true for Facebook too. I know what I post on the web, I know what I do on the web and I all consider them the same way I would do ANYTHING in public. I wouldn't share nude picture of me in a mall, at least if I were, I would be pretty sure that it's done in a relatively private means. > I think, hurting natural and more effective means of communication and self presentation. How can you declare it's more effective? I can organize events in a central place, way quicker and keep much more people involved in it that in any of the ways you talk about. You may be able to argue that it's not the most private, but that's not why I use Facebook. > I see this ending very badly. The good old slippery slope argument. I'm curious, what's the bad ending that you imagine? I usually like to use this counter-argument over that one: Hitler didn't ever need social media to kill that many jews... It's easy to manipulate people to hurt their community and go against what it's good for them. All you need is to control their fears. The funny thing your privacy fears is probably just as easy to manipulate. That's maybe what needs to be fixed, way more than anything else, though I would say that teaching people to be conscient of their actions and their impact is even better.
