Layer switching is the problem, not layering itself

[Piddy-uther (Piddy)]

Another popular theory is that you can determine your current layer by doing a /who in a capital city, and comparing the results against the /who your friend does. That doesn’t work because /who returns results from the entire realm, not just from your layer, and if the result set is too large it truncates the results before sorting them. This means every player gets different results, but those differences in result set have nothing to do with which layer you’re on.

I don’t want to explain why this is some spectacularly funny stuff for those folks relying on a hash of the Org /who, but, trust me…

It’s funny.
