As a researcher in the space of privacy and social networks, Facebook has been a great real-world use case of the pitfalls that these services need to deal with, and the challenges to researchers and developers to solve....Google runs a close second.
I contemplated leaving Facebook on May 31st (the Quit FaceBook Day) but decided not too. After all, I should be aware of the issues and technically capable to control my Privacy options on Facebook (and any other Social Network...)
However, today I feel insulted by the CEO of Facebook (Mr Mark Zuckerberg) as his recent negative comments about multiple identities on social networks (eg one for work, one for family, one for soccer mates, etc) - which in my view is essential for social systems to support as this is how humans naturally behave - with this quote:

“Having two identities for yourself is an example of a lack of integrity”

So, Mr Zukerberg thinks I lack integrity. This from a person who called all social network users “dumb f...ks” for sharing information.

Thank you Mr Zukerberg, you have made the decision to leave that much easier now.
