Sounds more like the world's least efficient way of querying the Median LLM Researcher about a given topic.

Every single <AI>pedia page on a topic will either default to median research-agent output (because the owner doesn't care to influence it), or be functionally equivalent to a AI-ghostwritten think piece because the owner cared enough to spin up a whole new wiki for it. In practice, a lot of owner-doesn't-care articles will be polluted by their prompt fiddling in chaotic ways that help nobody.
