I am interested in ALS disease research. What I did, is manually check each potentially interesting RSS feed and incorporate interesting ones into my RSS feed list and I wrote a small program to present it this list with a summary and an URL for each item. If I decide by reading the summary, that it is interesting, then I click on the link and look at the original article. IMO, the value is in the manually built list of RSS feeds (it depends on your interests), not in any RSS syndication software.
