I usually find that chatting to pax alongside me and finding where they are travelling to/from, the DLR is quite irrelevant for them.
A few recent ones :
Enfield
Maidstone
Heathrow
Rural Cambridgeshire
Apart from the poor American routing Antwerp-LCY-LHR-Los Angeles none of these are practical using the DLR at all.
And we live over in Beckton, just far enough away from a DLR station for luggage to be pretty impractical. By the way, have you ever tried asking a black cab to take you from LCY over to Beckton
