Reddit basically has a completely new userbase. It’s not only by age of user. I don’t think people have really appreciated the rate of attrition has been near total. The old userbase of tech savvy STEM college degree holders have effectively abandoned the platform.

They’ve managed to sell the platform on a whole new set of users. So it looks like the site has kept on plugging along. But really reddit has successfully relaunched itself. Based on the idiosyncratic lingo I see most often. The bulk of users came from Facebook. They don’t know the traditional redditisms so they use vernacular from the platforms they’ve migrated from.
