Agree on the radio point. It's made me realise that I often know what has happened more quickly due to the presence of a crowd.
On radio commentaries without crowd noise, it can take a surprisingly long time for a commentator to actually reveal a goal has been scored!
I can't find it now, but I think we polled on this during the early days of Project Restart.
Now we've become more accustomed to televised crowd-less football, when you have a choice do you go for crowd sound effects or au naturel?
