We are talking about how bad Wikipedia is. It's not all bad. If you just want to look something up out of curiosity, you don't always need to go straight to the proven manual of whatever. If you want to look up an actor's name, what's the big deal if you go to Wikipedia? I agree that it's not appropriate for academic papers or anything like that, but I don't see the big deal if you link someone to a Wiki on something that is within the general domain of knowledge. For example, let's say you don't know who Barack Obama is. So you go on Wiki and you come across:
Barack Obama - Wikipedia, the free encyclopedia
Wiki is enough to satisfy some general questions about who he is. He's the 44th and current president, etc. You don't necessarily need to go into the White House Archives to make sure that it is indeed reliable information. Wiki is not wholly reliable but sometimes for every day purposes you don't need the most reliable source out there. Just like you might spend thousands of dollars on camera equipment if you're a professional photographer, but if you're just an average person taking photos of your vacation you don't need the best camera out there. Likewise, if you're just an average person looking up who Obama is, you don't need the purest most reliable source out there. Wikipedia in that regard serves the purpose, just like the tourists whose $100 camera serves their need.
