The Help Center of Buddhism SE is very resourceful for including a list of resources, which in my experience the only site that make use of this section.
Putting content about the subject of the site (in this case, Buddhism) pushes down the content about the site itself (Buddhism SE)
→ This is true, but what is the harm? If the site itself is that important, why is the homepage allowed to be edited? Is it really true that only the latter is the one most visitors are going to be looking for? I'm a simple man. I need help, I visit help center.
That Help Center page is not curated by the community, there is no ability for community members to edit it, and most importantly, there's no ability for anyone to vote on it
→ There can very well have a meta post to decide what to write in there, so it has been voted on already and can still be continually contributed by the community.
