I think it's better to put aside the 'who' and focus on the 'what'. Knowledge, wisdom/insight can be found in any person, regardless of who they are, their credentials, their geography/location, or their ethnic background etc.
Yeah, the vast majority of content out there is not worth your time, but if you're here then you probably regularly browse Hacker News, and chances are the author does as well, so the author probably wanted to get his blog out there to people who at least shared that one thing in common.
Now putting aside the 'who', in this particular instance, judging the article entirely on its content: it's bullshit. It reads like someone bought into bullshit one year then was proven wrong, but only partially repented the next year. The fact the author arrived at such ludicrous conclusions about sleep in the first place leads me to conclude they're an idiot.
