Agreed. The design aesthetic actually works but the technical overhead in implementing is the problem. HN works so well because not only does it prioritize information density but it consumes less resources. The Reddit redesign pushes thumbnails, infinite scroll, and a useless right sidebar. Thumbnails waste space depending on the subreddit. Infinite scroll destroys the idea of a discrete "front page" which is core to Reddit being the front page of the Internet. In addition the infinite scroll makes no sense in the comments where on Mobile you can jump between top-level parent comments whereas on Desktop it's too busy loading child comments before you can get to the next top-level parent comment. The right sidebar is persistent and serves little purpose for a power user. The left sidebar which provides core navigation for a power user is useful when persistent but loads asynchronously with the middle, main content for it to be a consistent user experience.
