The ARRL book on Grounding and Bonding is very clear. Each piece of
gear has its OWN wire/strap to a common grounding point (a copper pipe
mounted on a wall is a common method, that being connected to the system
ground; everything to the building safety ground, more ground rods every
2x the depth of the rod).
Look at it this way, say a discharge comes in through your antenna, into
the radio, connected to your computer and other devices. Would you
prefer that energy goes only through the radio to ground (losing the
radio) or in a series through everything else in the shack too? The
'fan' mode you mention is preferred, give that energy EVERY chance to
seek ground BEFORE it passes through your gear.
Energy shunts (PolyPhase devises for example) at the antenna entry point
are another must. One per feed.
I suggest reading that book, several times (it's complex) for a better
understanding.

It seems that there are two ways of running grounding wires in the
shack: FAN - from a common ground point, individual grounding wires
are run to each piece of equipment; LINKING - a ground wire is run
from each piece of equipment to the next and eventually ending in a
common ground point. What's the group wisdom on the relative merits of
these two approaches to running grounds in the shack?
