It works. It supports pretty much everything you can think of. It doesn't crash in the hands of a casual user.
When we looked at a Wiki solution for an Intranet, this seemed the way to go. So we were quite surprised to find out all the limitations; for one thing that works, there seems to be another one that does not. Promising too much is the real culprit here I think. You should recenter and concentrate on making the core good enough, instead of putting an infinite number of questionable options. Having one standard template that looks GOOD on all modern browsers would be great too. The other problem is the lack of central design: each feature seems implemented by a martian from a different planet. It's a free thing, so no real complaints can be emitted, right...
