Expect an addicting algorithm that is fueled by ragebait (and if its anything like IG, coombait). The fact that it didn't release with an ability to time-sort tells you everything you need to know. Everyone knows how easy it is to sort by time, especially when stakes are low. Its anti-consumer from day 1.
The surge in people are likely influencers and people marketing their companies trying to get ahead of the algorithm. We've all learned the first ones to join a social media network are winners.
The people with novel ideas need to be convinced, and I'm not sure these people are ready to come back to facebook.
