I never said active users :-) We have ~500,000 active accounts as you can see here (I copied the source in the article, maybe you didn't notice it at first sight):
~50-60K are active on a daily basis.
I didn't open the results for everyone in order to avoid people being biased :-)
After the 15th of July it's gonna be public. Until then: spread the word! The more participants, the more representive the data.
Steem on!
