I don't see any innovative new revolutionary features, theme design and layout does not count.
Traditionally, forums are independent, isolated, and self-hosted. Users have to create a new account for every forum they want to participate in, and then check back for new activity on each one. And for admins, managing a server is the stuff of nightmares — as if managing a community isn’t already hard enough.
We’re bringing Flarum to the cloud. We’ll provide easy and affordable hosting so you can set up your forum in just a few clicks. You won’t have to worry about scary things like backups, updates, or traffic spikes. It’ll be the easiest and most powerful way to use Flarum for your community.
But... I like worrying about scary things like backups, updates, or traffic spikes. I don't like this single sign on stuff either, on any type of forum, so I'm not really sold from the spiel. I moved to xenforo because vbulletin 4, to me, was a broken wheel. Xenforo rebuilt the wheel again. This isn't even a circle yet, I'll come back in 2016.
