Algolia search for "blog directory" doesn't turn up the submission, but it does turn up in comments search, restricted to the past month, for those looking for search-fu tips:
Unfortunately for HN, titles make very poor search targets, all the more so because they're often obscure or obscured.
Comments offer a much larger target. Algolia's other features (searching by site or submitter / comment author), as well as obscure stuff like vote counts (submissions only) can be quite helpful.
I mine my own comments frequently, and that's a key benefit of using HN.
Thank you so much, that is precisely what I was looking for (my memory failed me regarding the background colour though, though there are purple elements). Thanks again, much appreciated.
Whether or not, it is what you were thinking of, I have found it super fun in general
