That is very valuable info, 3 mill created and 4 mill powered up, thats shows confidence building up on steem.. :)
Growth have been exponential also, just as the start of Facebook era.. 2 bill monthly active user on facebook but after many years, steemit on 300 ~ 400k active monthly user after just a year, that shows extreme good growth...
Glad person like you always keep on blogging to nurture the growth on steemit though.. Thanks... :)
