Whats all this about upvotes and downvotes?
Less Wrong works on similar principles to sites like Slashdot, Digg, and Reddit (it’s actually based on Reddit code). When a user sees an item they like, they can click a “vote up” link; when they see something they don’t like, they can click “vote down”. A highly-upvoted article or comment is displayed more prominently than a highly-downvoted article or comment, on the assumption that it is higher quality. Some people also use an article or comment’s upvotes to determine whether it’s worth reading. Upvotes and downvotes also affect the karma of the user who posted the item.
