I just heard that Reddit might be instituting paywalls for their subreddits. In the event that my favorite subreddits get affected I was wondering...

A redditor is looking for Reddit alternatives for the following subjects:

  • Pop culture/fandom discussions and recommendations (Ex: Avatar: TLA, Star Wars, Star Trek, Mass Effect, Ghibli, Muppets etc.)
  • Any and all subjects involving history.
  • Alternate history discussions
  • Movie, tv, anime, books, comic, video game, and theatre recommendations
  • Discussions and news with fellow ABCDesis
  • Worldbuilding and in-depth discussions about pop culture franchises (Ex: Mawinstallation, Daystrominstitute, Templin Institute etc.)
  • Specualtion on what the future might look like.
