In my regular RSS reader I often have the problem that some feeds are not full feeds, or some images are missing (In case they have some gallery) and I have to click out to the page, even just to verify I got the full text. That always kinda stops me from going the eink route where I don’t have a proper browser. Depends on which feeds you subscribe to I guess, probably works really well for long form, reliable feeds.
It's a web-based RSS reader optimized for e-ink devices (especially Kindles) that allows you to read blogs online via the Kindle browser, and download the blogs (directly on your Kindle or email it to your Kindle email).
And it does support fetching the full article using Mozilla's readability package!
