They tend to be reverted very, very fast. There are many things for which wikipedia is absolutely the most reliable and most complete source you'll find.
For the record, there's no one "at" Wikipedia in the sense that you mean. Anyone can edit, so crap like this happens frequently and is quickly reverted, as others have pointed out. Google is just linking to the most popular entry for "Duke University," and proper nouns almost always have a Wikipedia link as one of the top 4 or 5 hits.
On the other hand for many topics, wikipedia is an extremely well-researched collection of cited information. It's a fantastic starting point for researching. Let's take a nice benign article that won't get this thread moved to the PPB... Plate Tectonics. 30+ nice citations at the end. If I knew nothing about Plate Tectonics, there's a great place for me to learn.
Contrast that to the other 4 entries in the top 5 Google search and... well this one has 4 cites, the next one has zero, and two of them seem to be ads for books on the topic.
