Great article!

One small correction, if the number of user has grown by ~17,500 in 14 days to 60,500, then the growth rate is ~2.46% rather than ~2.9%.
This matters because if you start with 1000 users and you have a growth rate of 2.46% per day, after one year you have 7,117,677 users.
If instead you grow by 2.9% per day, after one year you have 34,010,403 users which is 4.7x more.
