Keep your grounds as short as possible and as many as possible. Isolation from input current and the ability to discharge while disconnected from input current/mains is the key. Good design principles in all cases. We manufacture on the cheap. Payback's a bitch.

I don't work on PCB layout design (much) myself, but have many friends and coworkers who do, and actually your advice is very applicable just as a general design rule, any nuclear threat aside.

Especially as frequencies increase for our circuits proper grounding is very important.
