I'm glad you did. Your input was invited to that post because I knew I did not represent your position correctly, and it also needs to be here for the same reason.
OTOH, time as a brane also explains many other phenomenon such non-locality, superposition, dark energy, acceleration of the universe, near death experiences, extra sensory perception, precognition, retro-cognition and so on.
Amazing that something could explain so much! It is too bad I cannot accept it. How much easier it would make life. But alas, I do not accept it, and in fact, I do not believe there are actually "three" dimensions, in the usual sense, and time, is not for me, a dimension at all.
The three dimensions are only a means or method of dealing with positional relationships, and time is nothing more than one of the qualities which describe the relationships between changes in position, that is, motion.
While the, "loss of a firm cause/effect relationship," would never bother me, since that is not that nature of cause in the first place, and since reason and volition are actually confirmed by the true nature of cause, there is no real advantage to these invented extra dimensions. They might be useful devices for picturing certain mathematical relationships pertaining to some phenomena of physics, but to reify them into actual ontological existents is just more mistaken platonism.
Now, for those not familiar with the term "brane:"
Brane: Any of the extended objects that arise in String Theory. A one-brane is a string, a two-brane is a membrane, a three-brane has three extended dimensions, etc. More generally, a p-brane has p spatial dimensions.
This theory would be very difficult to beleive except for the overwhelming evidence and commoness of the "p-brane."

Another quibble: Time involves a bit more than changes in position. It involves changes, period. All changes occur over time. If something were regarded as motionless, for example, the sun, it would still be changing over time. (I know, it moves, but you could arrange your coordinate system so that it's in the center.)
