It surprised me that nobody had added the “reads like an advertisement” template in all that time, so I did. Get out there and be vigilant.
The Sands article looks like it was written by a company employee / PR which I'm not sure is quite astroturfing. Depends on your definitions I guess.
It reminds me of a page I put up on the company Algenol which I thought interesting as it was trying to make ethanol direct from algae and sunlight and saying it would be cheaper than regular fuel. Then the whole thing got rewritten by someone like Algenol's PR and someone flagged it but I couldn't be bothered to re-edit the whole thing - takes ages. Then Algenol kind of failed, fired the boss and went on to other things. Not sure how the page is now.
