I've been a Feedbin user ever since Google Reader's shutdown. It's simple, it loads fast, and gets new features occasionally that I like. Does help that it looks nice af and not outdated too even after many years in.
Reader wise, always Reeder. I don't like it as much as the very earliest versions (I think it looks generic now especially on iPad), but I always felt like it was the best designed and the most reliable.
A bit of a shame that it's basically frozen in place feature wise. I remember double and triple dipping Reeder 3, 4 and now 5 and it's barely changed since.
I wonder if it is really about an insurmountable scope from years of development--or is that just a red herring on the fact that a lot of developers, particularly in the AAA range, have just forgotten how to make games actually fun to play that caters to their demographics rather than casting a web to the common denominators?
