Just that I came here from reddit where this was at the top of r/programming at the time. Full of vibrant discussion and upvotes.
On HN ... it was 22 hours old and all evidence suggesting that it was never noticed here (no comments), but very popular elsewhere (a lot of upvotes/submissions)
edit: it still is on top of r/programming with over a 1000 points.
Everyone reading this coming from r/programming? Am I allowed to say "hello reddit" on hackernews?
