I'm not sure how the ordering is done but I feel like the dataset is incomplete. Many "classic" links that get re-posted every few months don't show up and I barely recognize any in the first ~50.
I also think the threshold is too low. I'd go with something more strict like 50 upvotes and reposted at least 10 times.
Example: Currently at position 0 in the list: "Watch a VC use my name to sell a con (jwz.org) Posted 2 times, created in 2011". When I check the same link in https://hn.algolia.com/?dateRange=all&page=0&prefix=true&que... I get 4 results not 2.
