When doing the calculations i think we need to work with %ages.
1200 users per day seems huge today. But if we have 1m users 1200 new users would likely be less than users becoming passive and indicate decline. I am sure the grow is going to be a %age of the currwnt size of the network until we have reached a plateau.
On the other this is the first of its kind of business case combining social with blockchain. It is likelely flawed and there might be a better way. The qurstion is is steem the new yahoo or is it google. I feel it has found a new way of doing somethi g but i am bot sure it cannot be improved.
