I find some of the negative reviews here are appalingly biased and entirely devoid of any truth. I should know, because I have been reading it every day for a number of years. Articles that i have read are mostly very stimulating and well researched. Each article seems to be the original, and well researched work of the author, arising from their personal interest, knowledge, and experience. A very small number of items are provided by guest contributers who are promoting their own product, but these are in a tiny minority. I myself have submitted some articles which have been published, and i am a retired public servant with no connections to any corporations.
I suppose it is the hazard of being the #1 site that it will attract more than its fair share of trolls, though authors and other contributers are fairly patient with them. I have never seen any comments removed, so if anyone has been banned altogether they must be entirely appaling.
