This place has roughly 3,000 people and was intended to be an entire replacement for DaystromInstitute and StarTrek as they were going dark indefinitely. Well, within 4 days the moderators have walked back those statements and opened both subreddits up. I see no incentive for people to come to this website now and while a few may come here in the future, most people will go to r/startrek with 600,000 people.
There will likely be another influx when 3rd party apps die, and further trickling in if more and more moderators hang up the towel and reddit becomes more unmanageable with spam. It is difficult to migrate a whole community at once but I’m sure it will happen slowly, as more people become used to the concept of federation (you would think r/startrek would understand this “federation” though).
