I would guess the pragmatic answer would be that you could discard good candidates because of such reasons. However it may well be that there are enough good programmers who do meet your criteria that it is a benefit (in terms of time) to just ignore those that don't.
There is a broader issue though. If certain trends in hiring (that may be partly perpetrated by HN and the blogosphere) are preventing good people from getting jobs (to what extent this is true is up for debate) then what can be done by either individuals or society at large to somewhat reverse that?
Tech has always been proud to call itself a relative meritocracy compared to other more mature industries. As it matures how would we prevent the industry falling down similar pitfalls?
