What our friend what to remind about bbs, i want to add more thing here.
BBS network is similar and widely popular  who offered a srong mesages like facebook, reddit.Or can offer a group inside the bbs channel.
But is very different because BBS is a public online service, which means use the architecture distributed revenue model and a control of product.

But to use a service public, it is not very easy so for that they created a blockchain, developed later.

So architecture of BBS, present a solution  that uses public databases efficiently to create a network messages where is full distributed, while benefits comes from combines network.
