AideRSS determines which posts are most popular by examining the level of social activity for each post. For example if an article receives a lot of comments, that increases its "PostRank." If it's submitted to Digg, del.icio.us, or Bloglines, the PostRank goes up. Technorati links also help.
Now you can sort through your feeds by reading just the stories with the highest pagerank. You can peruse individual feeds or import a group of feeds to view together. If you submit an RSS feed that aideRSS hasn't seen before, be prepared to wait a few minutes. But if you enter a popular feed like Download Squad's you should get results immediately, whether you sign up for an account or not.
The system's not foolproof. For example some of the most commented on posts aren't necessarily the most interesting. They might just be controversial, or in some cases, contests.
