When you turn to the light and start to fully embrace the River of News, the sickening realisation slowly dawns that you might actually have been mistaken and partial feeds may just have some redeeming features while full feeds are indeed the work of the devil.
Full feeds potentially interrupt the flow of the river. The title alone isn’t enough to determine whether the article merits further consideration. Expanding the article should give you just enough to determine whether you want to read the full text.
This effect is spoiled by the lengthy verbosity of the full text feed for articles you are not interested in whatsoever.
The ideal compromise would be a 2 line precis of the article but Peter Scott is the only blogger in the universe who is thoughtful enough to do this.
