I'm calling it: Social networking is over

It was great while it lasted, but social networking is going away.
The idea was that you could sign up for a social network like Facebook, Twitter, LinkedIn, Google+, YouTube, Pinterest, Instagram, Tumblr, Flickr or Reddit and connect with old friends and acquaintances, make new ones or even interact with strangers about your life.
Except that Twitter was really a "micro-blogging" site,LinkedIn was about finding a job, Pinterest was a pinboard site, Instagram and Flickr were photo-sharing sites
