It's hard to have a public presence to say, >1000 friends on facebook. As a user since 2005 back in college, I witness my peers and my Facebook usage evolve from 'a social network with personal sharing' to a 'bare wall with a few instagram picture uploads / article sharing, and essentially a contact list'. It's sad, but inevitable - how personal can sharing be, when the friends list is over 1000 and some of whom are no longer actively in your life? Of course no one is to blame but the user (myself) that added too many friends. However, this issue is quite common in many users that approach their 3-4th year of using facebook; less personal sharing, more 'contact collecting'.
I wonder if what everyone thinks of a service that helps clean up the social media, or even more broadly, online presence of individuals. www.123people.co.uk tells you webpages/ social media accounts/ pictures/ articles about a person just by typing in first, last name and a region.
With facebook recently opening up email addresses for companies to target their ads (http://techcrunch.com/2012/09/20/facebook-crm-ads/). One can only imagine where our information is shared and sold to corporations.
It is a shuddering thought.
