I don't believe your statement is accurate.

[Edit: I interpreted "curated manually" to mean that dang picks each story that is on the front page. tptacek interpreted it to mean that, since users upvote and comment on stories, that's "manual curation". I interpret that as being "automatic curation", that is, an algorithm picks the front page stories, even though it's based on users' upvotes and comments. I cannot prove which of these two forms belter meant. Naturally, I prefer to think that it was the one I read it as, but I can squint hard enough to see tptacek's version.]
