Earlier quoted context omitted.
Was going to say this. My one gripe with HN is that people say incorrect things with complete confidence pretty regularly and you can only Detect it if you know the subject matter.
HN used to show vote count. In the past, you'd see something like your GP having a vote count of 14, and your parent (the correction) having a vote count of 53. It was super useful and helped to combat misinformation.
I undersand the reasons to do it, also, but I think you clearly elucidate what was lost... (T_T)
