In 2011, Phil Goetz wrote the post "What we're losing," which bemoaned the shift from applied rationality to theoretical rationality on the site.

Regardless of the era we're in, I believe LessWrong has gone too far in the other direction: To some loose approximation, every post is now about AI. Even assuming it's what you care about more than anything, even coming from a prior of "the highest-EV move I can make is to write and interact with posts on x-risk," you should heavily consider the benefits (both social and practical) of diversifying your intake and output.

Having norms around posting non-AI-related writing would be a good thing even for your ability to judge a person's output around topics you care about more, like AI safety.

When the entire discussion is indexed around one topic (or a narrow range of topics), it becomes very easy to adjust the way you're speaking and thinking to "fit" properly within the distribution of speakers around you. This allows for bad actors and poor thinkers to have an easier time hiding themselves within a group without revealing themselves as such. This is, obviously, bad: A poor thinker operating in good faith should have the opportunity to be corrected, and a community is far better off when it's able to be mindful of which people are acting in bad faith.

This is sort of a plea: Please, write some silly fiction. Write posts about getting better at thinking. Write some posts to help people get better at taking more general action! There's more juice to be squeezed out of the lemon of rationality, and when you're feeling anxious and can't stop staring at the end of the world, lemon juice will at least compliment the mood you're in.
