We are all eager to get Flarum up and running on our live sites but due to the fact that Flarum is not finished, Toby and Franz are not going to release it until they are certain it is ready or stable enough to use for a live site. Isn't it better to mitigate as many bugs now than to be constantly complaining about things that aren't working?
It's a double-edged sword really. If they release before it's ready, they risk the community complaining about how irresponsible they are for pushing something that should've taken a little bit longer. If they take too long, people complain that Flarum is taking its time and no active development is being done.
Patience is a virtue. If you can't wait then I would highly recommend using esoTalk as it is the closest thing you'll get to Flarum (and there will almost definitely be a migrating tool available once a stable version of Flarum is released).
