The two big advantage of the stubs is the hypertext function and the building add.
Hypertext function is much what it says, it is additional information that is useful, but would clutter up your submission if you had to explain it right there. If you are going to use the same "little bit" of information in more than one submission, it is more efficient and asthetically functional to use a stub for hyperlink purposes.
The Building function allows you to take existing small pieces of work and casually add them to other subs. For example Rydlin Steel from http://www.strolen.com/content.php?node=2975 could easily be incorporated in yours or anyones work. Go to Comment
Another 30 I used extensively ... pretty much with two hours notice, when I had to whip up the students and faculty of an academy of music, from which the contestants in a major musical competition were drawn.
