I haven’t figured out the curation thing either. I understand how you feel and I never got curated even though I felt 1 or 2 stories that I wrote should have had a chance. It feels almost like a rejection when so many writers I know have had more than 1 story curated. I know that my niche in writing humor is not as popular (judging from the Medium home page) as some of the others. I’ll keep plugging away at it.
