Oh... and what are the grownups using?
Anything that actually produces a schematic and not the abortion that Fritzing produces. People post physical layout diagrams produced by Fritzing and think they are posting schematics. They are not. For anything more than about six or seven components they do not convey anything meaningful. If you need a physical layout diagram then you should learn a bit more about electronics before doing something more than blinking an LED.
Personally I just use a generic 2D drafting program and draw my own components. Grouping and copy and paste means that you don't have to keep redrawing the symbols. You can put the pins on a chip where they need to be to make the diagram simple and easy to follow.
