Strictly speaking, it's 1,000,001th account due to the hidden very first user, @miners (id=0). So @quo (id=999,999) is the real millionth account :) See this: https://steemit.com/statistics/@blockchainstudio/real-one-millionth-steemit-user-and-hidden-very-first-user
ps, @ned I'm curious why your id is only 497, I guess you used other accounts before, right?
Looks like it is a typo. I ran a query and neds id appears to be 49. While at it I also got some details about the first 100 users on Steem https://steemit.com/steem/@gokulnk/steem-first-100-users
See my original post (https://steemit.com/statistics/@blockchainstudio/real-one-millionth-steemit-user-and-hidden-very-first-user) and reply to your posting.
See also https://steemd.com/@thisisnice7 which has id=49. (The reason why I didn't include the entire first 100 users was there were many of this kind of ids.)
Yes, the very first account of Steemit Blockchain Platform is hidden..
