I know what potentially Hugo-worthy works I created in the last year. I am unsure what pieces qualify for what category. In fact, I am even more baffled than I was in January 2019. Here are my bestguesses.
My Tor essays almost certainly fall under Best Related.
James Nicoll Reviews may also be Best Related but I think last year’s Worldcon counted them towards Best Fan Writer.
My Dreamwidth posts (links to James Nicoll Reviews aside) fall under Best Fan Writer.
Young People site may count as a fanzine. Or, again, best fan writer.
