One feature I miss from GReader is the ability to look at your reading stats. How many feads over x time, most popular, least popular, update frequency. While Newsblur tracks many of these stats on feeds, having a personalized stat dashboard would be very cool.
I’ve looked into doing something like this with the api and Chart.js (http://www.chartjs.org/) but I’m not sure it’s possible at the moment due to the API not sharing it’s feed statistics. Can you put this on your radar for premium members?
