JennyTal, why don't you actually contribute something to the conversation rather than taking cheap shots at di vosh who at least has an input. Remember, "Professional" pilots. 
Yes cheap shots. If you have a personal problem with someone, deal with it privately. This forum isn't provided for you to go around making snide comments about forum members. I don't see where Di Vosh changed the subject at all, he added some pertinent information and got a small bit wrong, whoop de doo! (and he happily owned up to the mistake.)
Dripping oil is not that common, but not really unknown either around a DH8 nacelle.
First of all, there is a load of drain pipes, some clustered to form a big drain mast on the lower L/H side of each nacelle (coming from various sections of the engine, some direct and some via a overspill reservoir), and another smaller one protruding from the tailcone of the nacelle (taking the overflowing liquid in case the hydraulic overspill containers in the main gear bays are full). If something comes out of those, maintenance tends to ask two questions: which exact pipe it is and how many drops per minute (as this is often limiting) come out of it. Usually, it is just the container that needs emptying when a maintenance base is crossed the next time; in case of more drops per minute than allowed from some of the pipes, aircraft have been grounded as well already.
If the drops are not from these pipes, chances are that it is no oil at all, but deicing fluid that accumulated in a corner during the last leg(s). It is fairly common that drops are seen on the open main wheel doors and also fall on the wheels in winter even a few legs after the last deicing. This is not harmful to the wheels and this would also explain the nonchalant attitude to Your observation the crew displayed on Your flight.

Jenny,
At least he put some meat in the game, the number of arm chair experts, such as yourself, that never actually contribute, at all, yet are critical of those that do, is disappointing.
If you are such an IR expert, get on the Council and set the world on fire. I bet you don't.
And before you ask, yes, I am a member of the "Di Vosh" fan club, the President in fact, Membership number: 0000001.
