Features for your rss reader project(add yours)

so, it seems everyone will compete on making a great rss reader now or reinvent it. so i want to share some features i think it will be great> feature(1): don't make users put the subscription link by them self, instead make the publisher submit the link and make a page for it (think of it as simple fb page)

feature(2): i want to follow some feeds with my friends, just be able to make group of feeds then allow to some of my friends to access it and can comment on feeds, this will be great(think of it as room you gather into it to read news). or you can do this in a simple way by making another tab on public feed comments shows just my friends comments - and also can have notifications about them.

feature(3): i can like any post, and if the likes number be bigger than (1000 - you decide) it shows on the homepage automatically(so users can read important news from the homepage).

please, if you have any feature you like to have, put it in a comment. thanks.
