I used NewsBlur some years ago, and left for G-Reader, then Feedly, then InoReader, and am just back to NewsBlur.
I’m glad NewsBlur is still around, because I never should have left. Glad to see the added features since then. Recently I discovered that my previous RSS reader was sending my Android data to a large social networking company (ahem). After installing NewsBlur (which IMO is the best around now), I discovered that NewsBlur does not participate in such shenanigans. I’ve signed up for premium to keep it that way!
