That's seriously positive progress. Loads of green and orange, and while it's still all veterans at the top, it doesn't seem too extreme.
I know March isn't included in the graph but it seems there were short spells where the blues were pushing greens out again (ie newer users but getting payouts) at both the beginning and end of April. Thankfully short-lived, and in fairness the beginning of April was a once-off anomaly.
Greens and oranges must always have space on that chart. Otherwise is a sign of poor health.
Green shoots are certainly positive for Steemit :)
