Attracting new Hivers isn't as easy as playing Uno or Yahtzee, but it's easy enough. The difficulty comes in their retention. If they built up their expectations of the Hive experience and realize the reality fallsshort of it by a lot, they will quit Hive. If they compared it to the Web 2.0 services from Big Tech, then it's even worse.
A posting buddy is a good idea, and I think it's been suggested elsewhere. It's good to have someone who can answer at least basic questions, and if the questions can't be answered then at least the posting buddy can point you to a source of information which can.
Even those of us who have been Hivers for at least 2 months have enough knowledge that we can share it with minnows, and there are things which even the whales among us weren't aware of regarding what Hive has to offer. If it's a hassle locating FAQs and other references, maybe we can kill two birds with one stone and post reference content which also gets earnings and engaggement.
If we make the learning experience fun for new Hivers and have them add to the legacy of knowledge about Hive, I think that would also go a long way to increasing retention rates.
