It's good advice. I did that one time with an obscure miniatures-related thing and had my own old forum and blog posts partially quoted back to me. Have much the same problem with some image searches where it turns out I'm apparently the only person who ever posted a painted image of some old oddball figure anywhere online. I should probably feel happy that I contributed some tiny bit of info to the internet that someone else might find useful someday, but really it's just depressing to know there's no one else out there with similarly obscure tastes.
