The writeup that is linked to is only a summary of which technologies should be tied together, without any proper explanation on how that should be done. The GitHub repository is from July, contains only a few weird UML diagrams, and doesn't have updates thereafter.
If you like the genre of fantasy, it's a fun writeup though. Especially the 'contribute' part.
Haha. Well, we built a decentralized social network, and bitcoin is a decentralized money, so we'll see, maybe someone can make decentralized media server. I mean, isn't GNU Goblin something like that already? And the web is decentralized ... so with a decentralized social network powering user accounts and social stuff, what's the problem? You can even use bitcoins and contracts to set up hosting agreements between people.
