Today, Groupon stock is worthless, and the company is doomed. Should the people in that thread be penalized for being right, but mean?
Vision is not "how is this guaranteed to fail?" but how could it possibly succeed despite the odds?
Which voice do you want to bring to this community?
However, around the time of it's IPO it was receiving so much undeserved hype that in comparison to THOSE lofty goals it appears to have failed. HN readers at the time were pointing out the hype, and I think that is a GOOD thing.
Nevertheless, I agree that the tone of the community could be better and I will strive to adjust my own comments to reflect that.
I can see they are skeptical, but I would hardly describe them as "mean".
Now, if that were a 'Show HN' post I could see where people may want the comments to offer constructive feedback, but that thread seems like a matter-of-fact discussion of the business model of the business.
