That's very good data. I've not learnt how to query the blockchain yet.
158K/30 is about 5K people per day
What would be more interesting to know is amongst those unique users, what is the distribution of STEEM/STEEM Power. Is there some way to get that data?
You can't just do that, they could vote every day for 30 days, would still show up as 158K. The query is to find the number of unique voters in 30 days, doesn't say they only voted once in 30 days.
Last 14 days of unique authors:
For last 24 hours it's 49,922 unique voters and 24,539 unique authors.
Yes, I can get that data, just more work.
I would pay you for that data - how much?
Basically I would want on a graph with;
x axis - steem accounts ordered from highest to lowest SP in account
y axis - steem power in account
