As evanrmurphy says, the citation is only there to link to the relevant HN thread; it's not implying that HN is (or isn't) a credible or reliable source. There's currently 57 external links to HN from the en.wikipedia.org domain,[1] though not of all them are used as citations. Wikipedia's Verifiability policy indirectly comments on sites like HN here: http://en.wikipedia.org/wiki/Wikipedia:SPS#Self-published_sources http://en.wikipedia.org/wiki/Wikipedia:SPS#Self-published_so... (and the section directly below, "Self-published or questionable sources as sources on themselves"). So for example, a comment pg made on HN would be something that would be an acceptable citation since his work in the field has been published in numerous reliable sources in the past.
