Considering wikipedia is an open source platform that already works... I guess there wouldn't be a need for it on nostr? What problem would it solve? I guess everything doesn't need to adopt nostr if it functions well without? Happy to be proven wrong if anyone has a good counter argument.

I wasn't specifically thinking of a Wikipedia replacement.
More like collaborative notes where you allow people to chime in on things you have written if you allow them too. The only way you could do this on nostr atm would be to read the comment and repost the note again, which would end up being kind of messy and confusing.
