I haven't decided if it's a troll or a person who thinks he is WAAAAY smarter than he really is.I'm curious. How do you know it's a troll and not a legitimate post? What exactly is a troll?
In any case, "a troll is someone who posts inflammatory, extraneous, or off -topic messages in an online community, such as an online discussion forum" (Wikipedia's definition) and we've had a rather nasty one here who claims he is a sleep professional and that nobody here has any business doing anything more than simply being a sheep and doing exactly what the "professionals" say no matter what kind of lousy treatment they are receiving.
Many of us advocate for opening up the "sleep industry" so that we can go buy our own machines at competitive prices and knowledgeably tweak our own therapy, but this guy is an excellent argument for why maybe that is NOT such a good thing. Which makes these posts smell a little more like something our infamous troll might think up.
However you slice it, "legitimate" is not a word I'd associate with this poster--his ideas are full of baloney.
