I get what you're saying, C. It certainly would be convenient and less confusing for a newbie to be funneled into ONE location for everything, have one best way, etc. But in my experience, nothing is that way.
Think of cooking sites / blogs, for example. Not only are they splintered by food genres but you also have multiple newbie focused sites, keto / paleo / vegan / wfpb / gf, budget cooking sites, gourmet sites. Everyone has a different take on cooking.
There are thousands of sites on meditation, yoga, guns, prepping, books, investing. You name it, there's a site for it... None of them are centralized. Even the government's sites don't agree, with different agencies having rules or laws that contradict each other.
It means we have to do more research and experimenting in every area to figure out what works for us, but imo, that's what life is about. And permaculture is no exception.
