For future reference, if you want to link to an interesting post rather than ask us a question, you really should submit it as a link rather than as an Ask HN submission. Ask HN submissions are poorly suited for this task — they're penalized in the rankings and URLs in Ask HNs aren't transformed into hyperlinks. If you want to post a comment with your link submission, well, that's what the comments are for.
