I really don't see any difference between using globals or properties

Scott pointed out some of the problems of using globals. One
particular problem in Rev is that we can easily share stacks with
each other. If you use someone else's stack (as a plugin, a library,
or as part of your application), and if there is a global in that
peron's stack that has the same name as one in your own stack,
unexpected things are likely to happen. That is why it's usually
advisable to use some kind of naming strategy for your globals. For
example, start all gloabls with "g" plus your applications name.
gMyAppUserName, gMyAppUserID, etc.
But that's only reducing the risk of name conflicts; it doesn't
remove it.
Custom properties don't have this problem as thy are tied to objects
(stacks, cards, etc.) therefore it's OK to have custom properties
with the same name. (the userID of stack "myApp" versus the userID of
stack "herApp").
