A digression, but it is the same high quality niche information that LLM's are after I believe. I'd be curious about what you think the trove's longevity in terms of relevance is? I ask as the more timeless it is the less chance it will be replaced, and the more valuable it is a s a learning resource.
I woulad also agree that it makes sense to split your time, personally. I hope some of those communities begin to shift, but it is a idol dream.
