Crowd selection isn't negative, in fact without it we d just be picking fruit at random in the forest with a good chance of dying of poisonning, instead of chatting online... on a popular forum we think like minded people also frequent, having opinions we suppose we'll be interested in on posts that are ranked by upvotes :p
Just because everyone believes the world is flat doesn't make it so.
At least in school in France we now learn not to blame ONLY the little guy voting out of despair, but also the unfair winners of WWI. Without that crowd deciding together to do something, anything, where would Germany be today ? Hard to be optimistic in 1933. And it drove the WWII winners into building a better post-war reparation program, not only explained by the communist scarecrow but also the lessons of the inception of WWII in Germany: revenge against abject humiliation.
When marketing enables them, the conversion rates increase by a significant fraction straight away.
Looking at increase in real dollars it becomes a hard sell to turn them back off again.
And these are not new either, just old sales tactics, applied to the new context. The pushiness of these counters etc remind me of the Hard sell[0] for example.
In fact I mostly buy steam games in the popular section to sort out the trash. Each time I choose a niche unfeatured thing it turns out to be random trash nobody wanted... unsurprisingly.
Why do you think your brain wouldnt rank a product with 500 views right now above a product with 3, or be wrong about such ranking ? I think it helps ignore shit, because it's rare you want to buy stuff nobody else wants.
Looking at something and actually buying it are different. If we really wanted to help the customer decide we might want to also show the number of customers that returned the item. Or wait: allow reviews of them ;)
Would it help anyone to see that "200 people are reading xwolfi's comment"? Not really. That's just because there are not many comments yet and says nothing about the quality of it. It's much better to rank comments by votes and let that affect sort order. "200 people found xwolfi's comment so insightful they clicked the vote link" is a much better indicator of quality.
