What if something happen to Theymos today or anytime. Bitcointalk gone? I can not remember the role Cyrus have. Do we have a setup which allow someone else to take control of the domain and the database in case anything happen to Theymos [Not just legal things but things related to health]?
I assume Administrator Cyrus also has server access. I have no idea if there's a backup plan for the domain name. Short-term, this will probably be okay (the chance of Admin dying this year is
no more than 1%). If the inevitable happens, there may be time to get a new domain name.
For loyce.club, if I would disappear, the domain is still active for a while. Hosting will keep going until something fails or someone pulls the plug. After that it's gone, and a domain squatter will claim the domain.
Regarding decentralizing a forum, what's the big deal of not becoming one because the centralized one seems to me a more appealing thing because that means there's more people that can easily access and participate to the discussion and most of the time, these types of decentralized forum's got something to hide.
For what it's worth: .onion sites aren't decentralized either. They all rely on a server with an owner, even when it's hidden.
Steem(it) had of course the problem that it had centralization problems because the governance token was highly concentrated on the founders. And of course the monetization system had several flaws.
It looked like a pyramid scheme when I checked it years ago, designed to make the first "contributers" money, and needing more people to join. I just looked at it, and it's still showing how many dollars each article raised.
But I think Steem(it) showed the principle of offering a decentralized publishing platform with web front-ends can work.
I'd expect a truely decentralized forum to work without website. Just a program you run, maybe like Tor browser, with a local database (or blockchain) containing all posts ever created. If most of the users use "light clients", I wouldn't call it truely decentralized.
So in general I'm not so pessimistic about the "decentralized forum" idea.
I am, but I'd love to be proven wrong.
