As I said, net labels are like GOTO. There are very specific situations where GOTO (or net labels) are useful.
They're also used in lots and LOTS of other situations where they're actively harmful.
Contexts like spark-fun designs, where the layout is almost always only one page is a situation where they're actively harmful.

I've done large, complex system designs without using net-labels at all. It takes a lot of thought about how to structure your component symbols, and was considerably helped by my EDA tool (Altium) having a facility to bundle multiple logically associated but non-bus wires into a single logical connection ("signal harnesses" - they're great), as well as very robust hierarchical design facilities.
It's absolutely possible to do, and you wind up with a much nicer schematic in the end, but it does take longer.
On the other hand, a site like spark-fun in particular sells educational components. The fact that they don't have decent schematics is really extremely disappointing.
