I built NewsBlur and it's always interesting to me to hear people talk about the UI as a retro feel, but when I look at the competitors, I feel they aren't dense enough with information. Minimalism has gutted our ability to process more than a bit of text at once and I think that's tragic.
the UI is an acquired taste i think, it has a very retro feel to it. i was mainly using it because it let you make nested folders of feeds
they also have an android app and its available in the fdroid store as well if you are into that kind of thing
