10 years later and I still can't let go. Shortly after they killed Reader, perhaps as a coping mechanism, I wrote a little wrapper that lets me use the Reader frontend on top of newsblur's API. The frontend is a pretty straight forward single page app, and ex-reader engineer Mihai Parparita had already demonstrated how to do this in the readerisdead[0] project.
