Here's my reading of what Justin meant:
Now we've been given the auction we know that dummy has shown 5+ diamonds and a club void.
I haven't thought through the inferences from the auction in detail, but on that basis, decent opponents will probably lead either
i) a trump, if they think there is a lot of ruffing required, or
ii) their better pointy suit, hoping to set up a trick in that suit before the other one is established. There would be a preference for diamonds, both because you are leading through the suit and because opener has shown a stronger hand.
The 8 of diamonds, if it's a true card, is either from the Q/J/10 (or the Q10) or from shortage. Good opponents are quite likely to lead from the DQ and would not find a doubleton diamond at all attractive. Bad opponents make what they hope is a safe lead, including doubleton in dummy's suit.
All opponents might well lead a singleton diamond, however.
