No, absolutely not! You can only tell that other non-experts agree in some path-dependent fashion.

I'll occasionally see highly-upvoted nonsense in an area that I'm expert in. This is very bad.

This is some kind of cognitive bias.

But that's a great opportunity for the expert to step in and say something valuable in reply. The high upvote count of the "wrong" response will lead to your response getting more readers.

The fact is we're already half way bought in to this "social bias". Otherwise just get rid of the voting altogether. Get rid of karma. In fact, get rid of associating usernames with comments. But I think everyone realizes, even if they don't like to admit it, that social context provides some value, even if not perfect.

These two things are very different. I'd be all for getting rid of karma, but usernames provide identity.

I.e. when evaluating someone's comment it would be good to see other comments they've made that might provide insight into their biases.

1) username <-> insight into what you think over time 2) karma <-> insight into how popular your comments are

I want (1) and not (2) for my own learning. (2) is interesting in terms of studying group behaviour.

No the don't, they provide a social signaling function that can be just as powerful as a vote count. When a "popular" name is attached to a post it gets read more closely and frequently voted up. If HN users were truly interested in letting the "quality" of the content stand on its own then comments would not have names attached to them and the content would truly stand on its own.

In other words, let the popularity of a username influence the visibility of the content. If you are suggesting that people (including yourself) actually go back and check out user comment histories with any frequency I think you are mistaken.

Karma is not just popularity, it is also a measure of perceived authority and insight that a comment provides to a discussion. The consequence of losing this signaling function may not have decreased the quality of the comments, but it has certainly decreased the utility of the comment sections at HN.
