Is the forum decentralized? No, it is not! Is Bitcoin truly decentralized? Do define democracy by the way as this forum is not.
Where is the technology to do that?
Will you make a blockchain forum? Will you pay a transaction fee to post?
Would you run a node for free?
Who is going to create a fucking front end with capable SEO to compete with bitcointalk, for free?
We have hundreds, thousands of forums in the internet. This is among the best of them. I don't think there is much to change here.
