Why do galaxies look like they spread out in a single plane (ie, why do they look more like frisbees than spheres)?

That is not strictly correct. Your question, I mean. Plz check this:

In short:
1) galaxies do not start neither end as a disk or a ball – so when we look into far, far away – we see many ages of these galaxies.
2) Even then – not all galaxies are flat, only the majority.
3) And even then – it is only the visible part that is flat, all together they should be closer to the ball, then a pancake.
