For what it's worth, I can attest that the Kingdom makes people interested in Hive. I'm running a tiny account and don't publish often but I do visit Hive every day, mainly to check out what is happening in the Kingdom but also to browse my favourite communities and bloggers. More than that, several times I sent Hive posts to people who don't have any idea about the blockchain but are interested in the events happening in the Kingdom.
In short, the Kingdom Without Limits is a place where Hive enters reality (or should I say meatspace?). You meet people whose blogs you've been reading daily or read about the events you took part in, such as the monthly Book and Film Club. So yes, maybe I'm not a blockchain expert but the Kingdom definitely has a fantastic potential to promote Hive and the current proposal deserves recognition.
