r/place is a site wide event where any user can place a pixel on the big canvas every 5 minutes or so. Communities will often coordinate efforts so their users can make art to represent their community. It looks like a lot of people have come together to make this Spez guillotine, which is fun.
Oh wow, I don’t know what I was expecting the answer to be, but that wasn’t it. That’s kind of neat, and also i am not surprised they are censoring things given the current state of Reddit. Bummer though. Why in the world would they bring it back at this point. What did they think would happen. This has been a wild ride.
Reddit is in a bad place right now (pun not intended) with engagement and content quality falling. To increase engagement and show the future shareholders that Reddit still "got it", Spez decides to bring back this popular event, which normally happens every 4 years (AFAIK, the next time it's supposed to happen is in 2024).
Basically you get one turn to place one pixel. By working together people and communities can make pictures and memes.
The Void is a bunch that just use black to consume everything.
After a little bit you can take another turn. So on and so forth.
In the past there were almost literal tile wars as communities fought for specific coordinates to color for whatever flag, void, meme or inside joke of the year.
