Hey, I think it's totally OK to use Wiki and the internet. But I'm of the opinion that you can't state that as an official reference. C'mon, look at all the garbage that gets posted as gospel on PPOT (or even this Stijn thread

). You can use it to point you in the right direction, but you also have to know where to find the answer in a reputable resource if someone inquires.
That it's now becoming acceptable to use sources like Wikipedia as references in schoolwork (you're not the first one to have a prof/teacher say it's OK) is a reflection of how lazy we've become, as a society. Who cares about knowledge anymore, when you can look it up? Who cares about using reputable , peer-reviewed resources when you can just check the interwebs? You know, there will be times in your life when you actually need to know how to fly the goddamn airplane, instead of just looking up how to do it for the first time while the thing is hurtling to the ground. (OK, bit of an exaggeration, but you catch my drift.)
