..... If the goal was to great
good content in "forum"-based Communities.
So far Xenforo is a forum only threaded chit chat tool.
It was in 2010 and is in 2016.
There is no indication Xenforo plans to move away from chit chat discussion threads to other more robust data structures.
In 2010 Xenforo was sooooo good and came out so fast with such energy I thought it was finally going to be the one. It's 2016 now. Xenforo is the undisputed king of forums (easily predicted). vBulletin is dead (a surprise considering the extent of the deadness). IPS is limping. WBB is WBB. Xenforo has not innovated away from plain jane threaded discussion. (Queue Xenforo staff saying .... "But we are just a forum").
Oh well ... let's see what the future holds.

As for
this idea ... it has merits ... but with no Concrete examples (the devil is in the details) I'm not sure the idea that a few custom fields for a thread will make threads into good review, classifieds, <insert beyond threads data need here> is realistic. I think it could be quite useful and seems almost like an obvious foot forward from plain jane threads.
Five years ago I thought Xenforo would show how they planned to "Move beyond threads" ... and display their vision of the future. But half a decade later that has yet to come. In fact we are waiting an increasing time for a ?feature parity release XF 2.x. The quasi-lengthy time to get 2.0 the door seems weird to me ... I do take solace in the obvious fact that Xenforo is the best forum today.
