Is there a party planned for the one million user milestone? Technology grows exponentially and Steem grew to 500,000 users to date. That is approximately 21 months since Steemit was launched in March 2016. The Wikipedia article claims there were 170,000 users as of May, 2017
170,000 users in first 14 months.
330,000 users in last 7 months.
We should see approximately 650,000 new users in the next 3 months if this pattern continues.
Yeah, social websites tend to grow exponentially, so I have no doubt that we get even more new users than the number you calculated ;) I think the incrising value of Steem and SBD will also attract a lot of new people here.
