So like probably many I use Google Reader to manage, read, filter my subscribed rss feeds. Subscribing only as much feeds as you can read doesnt really work. From time to time i delete some feeds, but it still gets more. Same with academic publications - more publishing people - more redundancy.
So the question imho is more, how do I find or better get notice of important rss articles? Articles for example with many comments on a newspaper inidicating a important, funny,... information. How do i find news in feeds im actually seeking for (keywords, topics).
Google Reader offers the sort by magic feature to sort the articles of a feed based on previous rated articles of you (done by like & star button in Google Reader). But despite i rated alot articles, the sorting doesn't look very different from normal chronological order. So this doesn't work well (maybe my subscribed topics are too broad or i have too many feeds, i dunno)
What options does one have to improve this, I'm even considering switching form Google Reader to another software with better filtering, noticing, sorting options.
News aggregator sites like slashdot.org with inherent social rating system i already use. Maybe a option just to switch for mass media information/world news to such services and only use RSS Reader for very specific feeds and authors? Im unsure...
