Hi Pablo, I posted this quoting your post to illustrate exponential change! Thanks for the material! You might want to look at my post to check my math, I guesstimated a monthly average growth in members of 4% /week roughly to calculate how long it will take at current growth rate to 50 million users (yes MILLION) the answer might surprise you if you aren't familiar with how exponential functions work. Curious how long it would take? read all about it
