Way back when I used to read usenet there were a few newsreaders out there that let you set rules for 'scoring'. You were able to tell the program to look for certain words and give them a number value. Then you could say to sort by the scores of posts. In theory the higher the score the more keywords it had that matched your interests. It also ment that stuff you didn't care about would drop to the bottom of the list.
As I start using RSS more for newspaper type feeds I find that I hate sorting through things, or there are regular posts from some newspapers that I really don't care about. It would be great to start scoring things based on things I'm interested in right now.
