I found a replacement for Reddit, it's called Lemmy. Lemmy.world is part of the Fediverse. I'm a bit late, but here it is for someone else to stumble upon. Lemmy.world is linked to this article.
Here's an except from Wikipedia:
The Fediverse (commonly shortened to fedi)[2][3][4] is a collection of social networking services that can communicate with each other (formally known as federation) using a common protocol. Users of different websites can send and receive status updates, multimedia files and other data across the network. The term Fediverse is a portmanteau of federation and universe.[5]
The majority of Fediverse platforms are based on free and open-source software, and create connections between servers using the ActivityPub protocol. Some software still supports older federation protocols as well, such as OStatus, the Diaspora protocol and Zot. Diaspora* is the only actively developed software project classified under the original definition of Fediverse that does not support ActivityPub.[6][7]
