Wow, though reading comments and viewing images from inside a RSS newsreader seems pretty sleek, I'm not really sure if I'm all for that.
I still think the killer functionality will be a properlly done post and news source rating system. Comeon, I want to trim down the ammount of information that I have to digest to get a picture of what everyone is talking about.
How long till we learn from slashdot's threshold system?
What I'm really looking forward for is a reader that will allow the community to collaborativelly rate each post. That way you'll be able to filter noise in the aggregators based on both general consensus (or dominant ideology) your trusted consensus (the people you choose to trust and allow to influence the filtering in your own feed) and personal preferences, creating your own, unique but communally balanced blend of news. mxna rates posts based on click-thourghs, but with this system a popular post doesn't mean it was a usefull one, most time popular posts are the ones with sensasionalist titles which end up having zero content.
The ammount of raw information being bombarded at us on any channel keeps on growing exponentialy, but still, there's nothing wrong about that. Have you ever tryed watching 180 tv channels at the same time on a video wall? no, you always tune into one and if you think about it it's always the tv show that everyone is talking about, and the one that you personally have interest in.
Current RSS Newsreaders are excellent for that, but they only allow you to tune in into channels (each blog) but still don't really help much in trimming the ammount of information a step further.
All that said unless I missed the point and involuntarilly went over the information telling me that something like this actually exists today:P
