We post on most of these threads and our batting average for hiring from them is MLB respectable. We have below-average turnover; we're just growing. Every single thread we've posted on has introduced us to candidates we were thrilled to talk to.

HN is our single best hiring vector, both in quantity and quality.

I think you can safely assume that people are getting hired from these threads.

(I think posting the job thread on weekends is counterproductive and don't post in those months).
