Breadtube if it didn’t suck.

Post videos you genuinely enjoy and want to share, duh. Celebrate the diversity of interests shared by chapochatters by posting a deep dive into Venetian kelp farming, I dunno.

Low effort / spam videos might be removed, especially weeb content.

There is a cytube that you can paste videos into and watch with whoever happens to be around. It’s open submission unless there’s something important to commandeer it with at the time.

A weekly watch party happens every Saturday (Sunday down under), with video nominations Saturday-Monday, voting Monday-Thursday. See the pin for whatever stage it’s currently in.
