It's not the Encyclopædia Britannica. I could see if this site was expected to be source or reference material as you suggest. Maybe I'm missing something and it's supposed to be authoritative. But I don't see why someone would be full of worry that a random web site on the internet is posting information that may or may not be accurate. Happens all the time.

Thanks for the explanation. I honestly wasn't sure what could be causing "plenty of worries" in this context. At least now I know what the issue might be.
