It could start by having a pinned post thats updated with links to specific-topic posts. It would be a low barrier start, and it would make sure new topics (like washing dishes) show up in a feed. (If they don’t show up in a feed I’m probably never going to read them)
Once there’s enough content it’ll be straightforward to convert to a wiki.
Topics I’d like to see are; short/simple guides to rainwater collection and solar panels
