I know, right! This is a great way to forge strong communities of like-minded individuals. Groups can build their tribe and, from what I understand, because these tribes will be nitrous instances of Steem, they can ignore hardforks of the main Steem blockchain, and create their own rules instead. Much like how Palnet.io is already implementing a 50/50 author rewards/curation split even before Steem's Hardfork 21. And as you pointed out, as these tribes multiply, so do the earning opportunities for Steem!
The last few days have really been full of exciting developments for Steem and it almost came out of nowhere. I mean, I feel like it has overtaken most of the Steem conversations. From Steem-Engine, to Palnet, to DECs, and now Splintertalk. It's just a great feeling to have something really positive to look forward to about the blockchain, without having to explain why.
