How would a rss reader for people look like? Would it be able to rate/rank items accordingly to the probability that I'm going to like it? The main problem with rss feeds is the same as with many other media formats: people try to meet the standard volume (at least x posts per week) even if they have nothing interesting to say. Most rss feeds suffer from the same problem that also hampers novels that have to be X pages long, movies that have to be 100 minutes long, or CDs that have to have a minimum play time etc. even though the quality of the material would suggest something shorter.
