Except in rare cases (like Wei Dai's Fair Division of Black-Hole Negentropy) I'm still using article upvotes to partially determine whether to promote articles to the front page - some informal mixture of "number of upvotes" + "editor's judgment". I mention this because while comment voting is still healthy, the amount of article voting seems to be dropping off. As of now I'm still drawing the inference that no one thinks "Are You Anosognosic?" worthy of promotion, or wants to see similar articles from me in the future - since other articles have at least gotten more votes than 0. But as the amount of article voting diminishes, it becomes harder to trust such inferences. Maybe people liked that article (or others I haven't promoted) and just didn't bother to upvote.
I'm posting this observation just in case people figure that upvoting articles doesn't make a difference. It does. It also encourages authors to write similar posts in the future, or alternatively not.
True -- but this is not an instance of no one voting (I assume "Are You Anosognosic?" has received some downvotes as well because it is under 'Controversial'). The purpose of voting is to improve the signal to noise ratio, but there is so little noise on LW that voting is really only distinguishing between good signal and great signal. Nobody is afraid that not voting will diminish the current signal to noise ratio, are they?
