I love @kaymbolden, but I had a different experience with P.S. I Love You. When I had a piece published there, I couldn't even find it! The pub was so huge, my story was lost in the shuffle. I didn't get many more views on P.S. than I did on my own page, and I never submitted again.
I didn't know PS was funded by Medium. And I don't know why they are stopping funding now. Medium strategy is changeable and inexplicable. So perhaps the best course is to make your own way. It sounds like you are doing just that. CONGRATS on The Virago! I will check it out. You don't need to be huge to be meaningful. In fact, sometimes super size dilutes meaning.
