I know it's crazy to think there's anything anyone's missed on the entire Internet
There's enormous amounts of information in old books and newspaper articles which, as far as I can determine, has never been put on the web. Of course, most of it isn't of any commercial value. But some of it is relevant to important social, political and enviromental issues, especially in providing a historical perspective. I found that when you do add anything new to the web, even if it's about an obscure subject, it gets scraped and spread around, and eventually gets turned into a wikipedia page.
