I think it's another HN bubble thing, though. It's been a few years since I was out interviewing, so maybe it's different now, but I would honestly be shocked if I interviewed with someone who even knew what "Github" was. Obviously it depends on the specific field you're looking in -- if you're interviewing with startups in San Francisco, then sure, the HN view might be helpful, but the vast majority of companies are nothing like that.
