I actually find that for most feeds, I dislike chronological sorting. It is a good default, but I prefer to have rules that promote certain authors and keywords. For example, on my Arxiv feeds, I promote certain keywords, and "autoread" everything else. On news feeds, I promote articles about my specific area of the city. I use Gnus to create my own recommendation engine to do this.
