@xj9 It's not centralized, there can (and should) be multiple rooms. Starting a room is very easy, so this means it is likely there will be many rooms. And rooms don't need to be permanent, they can be created and destroyed. It's ephemeral, without harming the social graph.
@xj9 DHT discovery doesn't come for free: (1) in a DHT you share your IP address with potentially hundreds of other peers, and also to peers unrelated to your interests, whereas with rooms you share your IP only with the room administrator, (2) DHTs doesn't work consistently across all network connectivity situations (mobile, whatnot).
@xj9 It's fixed infra that can fail, but when it does, you can set up a new server and literally nothing would be lost in the process. More importantly, rooms are not meant as the *only* way to access the Scuttlebutt network, it's one more way of accessing it. It can (and should) work in complement to pubs and DHTs and LAN, and as such it would make the network *more* resilient, not less.
