The author of this article seems to have no understanding whatsoever of what Digg before their distastrous v4 launch in 2010 and Reddit, now are. Reddit and Digg are hiveminds where you go to find out what's up on the internet at large. This <i>is not</i> where you go to find out what your friends are doing (Facebook) or what the blogs and personalities you already know about are doing (Twitter.)<p>Think about it as concentric circles. Facebook is the tightest circle—people you largely actually know, or interact with on a personal level. Twitter is one more out—people you're aware of, and whom you like, some of them you know, some you don't. If those networks are like the orbits of Earth and Mars, Digg of old, and Reddit are like the orbit of Pluto.<p>Facebook and Twitter <i>did not</i> kill Digg. Ask anyone who used to frequent the site. Where to find this person? Why, on Reddit of course. If Digg had had their botched v4 launch <i>before</i> Reddit was a legitimate competitor, they might have had enough time to clean up the mess and get the site back on track. But instead, they launched a product that betrayed their community, who readily moved over to Reddit, who largely welcomed them with open arms.
