Why? There are tons of perfectly good rss feed readers. I've never understood this one. I was a heavy Reader user, seamlessly switched to Feedly like the day after it was spun down, and never thought about it again.
Looking back, I guess it served as a kind of instagram/facebook feed, but for the internet that I wanted to see (which would differ from time to time, sometimes i want webcomics, sometimes I want ffffound <- this is largly something social media has yet to pick up on, the ebb and flow of what our attention wants). But no social media has captured my attention like Reader did...
I use Feedly now too but I still miss my Reader band.
