Reason to build: I've seen few blogs that link to HN as primary forum and think it's great, but AFAIU that forces you to update post after publishing to add HN link. With this you can just link to discuss-on-hn.xyz/go and it will update itself.
Inside it uses HN Algolia API [0] to search and redirect to first item and in-memory hashmap; I'll add rate limiting tomorrow, right now I need some sleep. Also this is my first Common Lisp project ever, that turns out to be quite fun.
