Now that most people have been taught to use their real identity on social media how can you meaningfully separate these things? The lines are even more blurred if you're applying for some social/RH position. Even for a coder you might want to google a bit to look for contributions to open source projects or mailing list posts since that can be a very good way to see how the person actually works and communicates. While I believe that the big data giants like FB and Google ought to be better regulated I also think that you have to make the users aware of their responsibility. Don't put anything publicly online that you wouldn't be comfortable seeing in the front page of a newspaper. And do the same thing when posting pictures and videos of your friends and family. If you don't value your own privacy Facebook won't do it for you.
