At the very core it comes down to whether or not people will have always-connected device that can do simple tasks for them. Imagine a layered webs-of-trust from Layer 2 up. Person P1 can trust router R1 (the one they use at home) to accept messages for them. They follow P2, P3, P4 on this future Twitter. P2 may entrust their friend's router. To deliver messages from internet piece to internet piece you use the WoT to make sure that the packets you are sending are from trusted computers. Some institutions, like banks, say, may be more forgiving than others because they have a profit incentive, so if your home computer gets hacked they may disallow your packets for a while, but once you get a fixed computer you're off to the races again.
Forums could be done in a multitude of ways, but what you are primarily asking for is for open forums. But it isn't possible to secure an open forum. We see this over and over again as spammers push their garbage down everyones throats or gloss it up by astroturfing. We can have relative anonymity, for example, Person P1 signs trust to Alias A5. We could even use something more complicated like what Monero does, but I worry at some point it will just turn into another form of money and that is antithetical to the whole model which should harshly punish people and devices that supply trust for cash.
Anyway, I know its a bit abstract, but you could have a forum. And it could be more or less realtime (since I'm getting updates pushed to my own device) but you're right, it is way more complicated and wouldn't truly be the same thing.
