Just like Digg, digg is still technically around since the website is still up. Though it's not really Digg anymore. It's just some random news site now, you would never guess that it was once one of the most active forms on the internet.
That's where Reddit is headed, any arguments trying to push otherwise are pure cope by Reddit addicts, who just want to keep scrolling forever and don't want to have to start over from the beginning on a different platform that might be alien to them. They're going to have to though, even the people who were loyal enough to stay with Digg until the end had to move on at some point.
