csf I can't get over how well done FluxBB on Textpattern has been modified to look; it's amazing and inspiring.
I agree with your previous point as well. Although Flarum is a new competitor to a long list of available (and stable) forum software, you really have to compare it to other free options. XenForo, IP.Board and Burning Board should be categorised as a paid for alternative but not listed in the same class. But as the topic states, they are still a competitor regardless.
There is no doubt that Flarum already has a large fan base but any more will only improve its foundations. Everyone is waiting for a stable version to hit the shelves so until then, I am more than happy to use the beta software. Having said that, larger communities and ones that rely on their forum will wait it out until a stable version does eventually hit.
It's almost there, I can smell it. And hopefully in time for a new project I have already started planning in the last couple of weeks.
