Looks like Gnus for people that don’t like Emacs. With Gnus, you can using scoring to make your own algorithm to display news in a user defined way. The Gnus manual calls this artificial stupidity.
If I want to write an algorithm to sort articles in HackerNews by upvotes and time, is the upvotes information available to Gnus? Assume the RSS feed has a customized field called <RSSBrain:upvotes> for each of the article, does the algorithm have access to that data?
And does Gnus need to get all the articles in a folder/feed and run the sorting algorithm on the fly? If so it seems to be a performance concern. Would love to know how it works in real life.
