I don't argue to not start this project on nostr at all but the data ... Wikipedia is a giant treasure trove of indisputably valuable content that I bet will get copied in by some bot at some point anyway, just to pre-fill the pedia with something to grow from. Why re-invent all that content?
Someone can build that bot right now and transform all of Wikipedia's content into nostr events. That's not the hard part.
you could just have a hyperlink forward to the Wikipedia article of whatever article that you're looking at at the top
