I don,t have any experience with RSS on eInk, but I would rather that my RSS only contains only the title and the "pitch"(very short summary of the article, or the first paragraph). If I'm interested, with a single keyboard shortcut, my RSS reader fetches the article text for me, so I still don't have to visit the site and read the whole article from within the reader. I use InoReader, but I know NewsBlur (and probably others) has the same (fetch article text) functionality.
