Indubitably! These kinds of submissions are the only reason why I return to HN daily and wade through the endless submissions that break the off-topic guidelines [1], and yet get upvoted anyways.
Our long term plan is to make for less wading and more pleasant strolling.
If you (or anyone) notice an excellent-for-HN post that has fallen through the cracks, please let us know at hn@ycombinator.com. We're thinking of starting a search-and-rescue program for the tragically overlooked.
