And I didn't suspect you of chasing NRVE! Just sharing my opinion of what might be currently motivating many of the referrals.
I'm not 100 percent sure what the Team sees as the ideal adoption rate right now. It is possible that they don't particularly need the platform to grow much more before launch, and are hoping to accelerate growth at that time. They might have an ideal target for membership numbers for each stage of their release schedule of feature, leading up until Beta Launch. That is how I would be doing it, and it is a common sense approach.
So if that is what they are doing, I can only assume they will tweak their advertising, and potentially other things including referral rewards, if they find they are falling short of their ideal targets for each stage.
Personally, I think it is only once content drafting is in place that it makes sense to grow faster than we are growing now. That feature is scheduled to be released this month (January 2019). It is with that feature in place, that every new member will translate into more content on the network at launch time. Right now, we have a large amount of niches, and enough voters that many niches approvals are being determined in a single three day round of voting, so no huge need for greater numbers until content drafting, in my opinion.
But then again, this may be a situation where more people is simply better, even now. There is certainly an argument to be made in that direction - but not sure if the Team will feel it is strong enough to divert effort from their development priorities. Who knows! Great that we're here hashing it out for them to pick over and see if there is anything they have missed!
I'm glad we have you with us!
