You're missing the point of contact lists.
Also as I said this is a niche. Your examples are tiny communities. Even Splinterlands is a micro system compared to the world of card gaming that it caters to.
Dedicated people pursuing rewards will always exist.

Masses however want an already finished product and content to consume. The rewards clearly hasn't enticed them over here. In fact imo the connectivity won't save this chain. CONTENT IS KING and there's just not enough here to retain a stream of new users while they (MAYBE) take a step into the abyss to play with the tokens.

That's why keeping users on Hive is so crucial. Just thinking that tools for builders is all it takes for 'token moon' is ludicrous. Those dapps need consumers/audience. That's Hive's fundamental flaw. User attraction and retention.
