I rather like the shitpost bombardment. It's the type of thing that creates a party vibe, and it could attract more than a few eyeballs to peek and linger. As the content can be somewhat dry in a community that's just starting out, this helps to normalize the place, make it more familiar to visiting eyes.
This current shitposting challenge sure as hell beats a barrage of anti-reddit, anti-musk, anti-zuckerberg posts, as well as "how does this [Fediverse/instances/posting/etc] work?" dominating the All page.
