Is basically the problem of threads-based forums repeated in the blogo/HN-sphere... It would be cool if the best blog-posts could be somehow preserved, and shown when somebody is interested in them as if they were new, + personalizing the news/reading experience (Thoof comes to mind here). In the past years I built this (http://www.logilogi.org http://www.logilogi.org), as a hobby/passion-project, but naturally it has not taken off either, as threads and/or "expiring the attention" that is given to posts, have the advantage that they focus readers on a limited number of posts, increasing the likelyhood of attaining critical mass in discussing/replying to them. So there is a dilemma here...
