I think it will be a case of shock and horror. From my understanding not much did happen for so long and the only change was the price of Steem attracting new users. Everyone was waiting on SMT's from the Steemfest 2 years ago and nothing happened. I think I joined at the right time if I look back as since March there has been a decline of users, but also the emergence of all these new sites. You leave now at your peril.
