I'd almost ignore the traditional news industry. You're trying to do something new and many won't understand it or have useful tips in 2019. Just make sure you have easy to find and share deep-dive topic pages and you'll soon discover whether people are interested or not in this style of presentation.
Yep, exactly like that. IMO you want to be the single best page on the internet for something like that. More interactive than a Wikipedia page, broader content than a news item, etc.
