I don’t believe the Partner Program had many changes before. It’s fairly new — a year or so old. I didn’t join until May but my income has gone up steadily since then. If the current track stays the same, I will make way less than half what I made in September. The changes hurt short pieces and poetry the most since income is calculated partially on how long someone looks/reads what you’ve written. A poem, particularly a haiku, may take seconds or a minute or two, even though the writer may have spent as long on those short poems as some spend on long articles. It’s nonsensical.
