I suppose it's very difficult to tell the difference between astroturfing and a group of people who feel compelled to voice an appreciation for something, perhaps notified by a "Hey I posted this to Hacker News!" message on a mailing list or a Twitter profile they follow. In this case, yes, I would fall into the category of people (as you described in your comments elsewhere) with a strong opinion and confusion over why someone would think otherwise. Except, of course for the author of the article and friends.
