I am preparing for a webinar tomorrow in which I hope to explain RSS to the participants. It used to be easy. You had feeds, you had aggregators, the principles seemed clear. Now it has all got muddy with things like Paper.li and Flipboard "making things easier". But they are not easier, they are more managed.
In the attempt to make things easier they have changed the nature of the thing you are trying to do. This happens all the time. Because people are disinclined to make the effort to learn how to do a worthwhile but complicated task we make things easier for them and in the process lose something.
