@hpinsley, cool concept! The preview shows just the placeholder though - RSS fetch is hitting CORS since it's client-side:
Cross-Origin Request Blocked: The Same Origin Policy disallows reading the remote resource at https://rss.nytimes.com/services/xml/rss/nyt/World.xml. (Reason: CORS header 'Access-Control-Allow-Origin' missing).
Moving it to an API route would fix it.
