Keep tracks as short as possible.

Sure, but not at the expense of having crappy non-orthogonal tracks at
any old angle (as shown on your PCB software) - yuck.

Why not? You say "expense" as if it matters.

There are several reasons why professional PCB designers don't do it:
a) Aesthetics, it simply looks ugly and unprofessional. If you did
this in a professional PCB design house you would be laughed out the
door.
b) It can take up valuable routing realestate when the track density
gets high enough.
c) It can make future editing much harder, esp in the case of dragging
tracks together for minimum DRC clearance for the purposes of freeing
up realestate as in b).

Those are the reasons why *all* professional PCB packages will limit
you to 45/90 tracks by default, and most professional designers will
never deviate from that.
