Sorry to "bump" this topic to the "swamp surface"
but I'm glad I found it.
I was looking for validation of the way I use worksets, and explain to others.
I too.. use worksets to control visibility of groups of stuff, I try not make too many.
Yes there are other ways to control what you see, view filters etc, but this is by far the easiest way to handle groups of stuff from many different catagories, and it can be incorporated into view templates as well.
