I'm not a regular USA today reader, but from a brief look it seems like in the EU version only the most recent ~30 articles are "reachable" by clicks from the home page.
p.s. the EU version is on it's own subdomain, maybe you can reach it from the US too: https://eu.usatoday.com/
Whilst all the articles seem to be accessible if you know the exact URL, the homepage only shows the latest stories and there are no links to different news categories.
Also, the articles seem to be missing links and the videos are not available.
If all you want is the text of the articles and you only want the latest stories, the EU experience is probably great. But if you want more, you're probably going to be disappointed.
Hm, what if you’re a reader looking for journalistic text articles, is the same content available on both?
