I've recently been thinking that Reddit holds a lot of potential that has yet to be tapped or expired. The recent pivots post CEO change (mobile app, redesign, crackdown on garbage) speak to a future where currently fractured private communities such as those on Discourse or Slack can find a more publicly accessible presence. Facebook Groups, while immensely popular, currently falls into the same opt-in, zero-discoverability category.

The timing couldn't be better with the hollowing-out of Tumblr.
