Thanks I was just thinking about it today. 13,295 in last 7 days is pretty underwhelming but I think its quite normal. Looks like more than 1 out of 10 people stays. This racio sounds bad but Steemit is not for everyone so many people just checked it once or tried to post one or two articles and then gave up. Some people also lost passwords, created multiple accounts, forced their friends/family to start accounts which they dont use etc.
It would be very interesting to see these numbers in time graph for a last year or something like that. So we could see if the active numbers are growing or if its diing out.
