"Did you not read the part where staff say they don't feature all posts in a given tag but algorithmically choose a subset to feature?"
Maybe we're talking about two different things because my posts have always shown up under the subjects that I choose--until now where NONE of my three posts on the economy are showing up.
"For god's sake, how much time do you think people spend on the reader?"
I have no idea, but that's where all the readers I have come from. And that's where everyone I follow come from (what I read from the reader not Google). If this happened to all of your future posts, you would have a lot fewer views and followers--and I'm sure you would complain and have the issue fixed.
