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. Also media criticism, bite-sized versions of left-wing theory, all the stuff you expected. But I am curious about that kelp farming thing now that you mentioned it.
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.

I saw human metapneumo plenty of times when I worked pediatrics, no idea why its coming up now. We had a big wave a couple years ago too.
Its little known to like the regular public but thats cause its like RSV for healthy adults - you get an annoying cough and feel vaguely bad for a while. It hits kids and elderly hard, of course, and anyone immunocompromised. The pneumo part is because it often leads to secondary bacterial pneumonia.
Im a little surprised its being reported on at all tbh
I caught a particularly bad strain once when I worked on an Infectious Diseases ward. Way before COVID19, we had a suspect TB case that turned out just to be HMPV in a traveler. The senior registrar was like "it's fine we can stop all mask precautions it's just human meta pneumo virus!", a week later there was barely any doctors, nurses or allied health left to turn up. I've only ever been that sick when I've had covid19 or influenza.
