Security of what data? When you re keeping everything open, there is little fun in hacking through it. Facebook is a complete open data system with clear and robust APIs. I am yet to see if someone is able to hack away itno its database. And even if someone does, what advantage does it give to the hacker. 1 day of downtime 🙂 lol funny, it sounds.
According to me 'security' is a marketing buzzword which comes from a closed era and has been cashed upon by likes of Microsofts and Oracles of the by-gone decade. Of course the opinions are subject to expert's analysis but social media is no rocket science.
