Google+ introduced a new (shiny) feature recently called Custom URL's. Up till now people had to communicate these long URL's if you needed to find someone on Google+. Mine for example is: https://plus.google.com/u/0/105217840082627216167/. Not a real slick way of presenting yourself on the Interwebs. When you log in to your Google+ account you get the option of getting one of those URL's for 'free'. It basically is your screen-name in the URL.
Mine would be http://google.com/+GuillaumeRaisonnable/. Would be, because, I'm not getting mine. The reason for this is that you need to leave your mobile phone number with Google for so-called verification purposes. By doing this I would be giving away another piece of privacy for something shiny. Something a lot of other people will be more than willing to do so. Just remember that the NSA never had it any easier since the arrival of social media to violate your privacy.
