I'm only interested in two features of SuperNet: BBR and Pangea Poker. But all I hear about them is a deafening silence.

https://nxtforum.org/nxtventures/pangea-poker/?PHPSESSID=0vddpb3gsi5knqvbbm6ccepma7Notice that James keeps adding core coins with 1st class Dev teams...
Elite Devs are the scarcest commodity in crypto (so it's a great meta strategy).
BBR is a poor example...
But most of the other coin communities (FIBRE, VPN, VRC, now SYSCOIN) are excited to be part of SuperNET...
And the individual SuperNET Alts have done very well as trading vehicles... but not BBR it seems.
(I don't follow CryptoNote coins on principle as they propagate much of the Toxic Culture in crypto...
See IceBreaker posts... and 99% of Monero Truther posts/spam).
Many complex projects are significantly delayed Etherium, MAID, Storj, etc...
I think James is implying once the SuperNET core is done... many things are in place to move fast.
