However, if you do some quick math, you will see that 100M signups (defined by install the app + click a button that says signup with your Instagram account) out of 3.8 billion monthly active Meta users is 3% of their users" Speaking of math, MAU means active at least once per month, which can be as meaningless as being triggered by a notification. Also, a month is longer than a week. The 3% signup percentage is nonsense because only 1/4th of a month has passed. Even after a full month it's a guessed number because you have to know how often the "sign up" banner was served (and seen) to actually active users. Calling a 1 million new users PER HOUR "not a slam dunk".
