The citations on Wikipedia articles are often either broken, in a foreign language, or not up to an academic standard. However, following this practice is what eventually lead me to stop using Wikipedia for anything. When I tried to trace the citations to make my research easier, I found it actually made it a lot slower because I kept running into junk. Before I actually paid attention to the citations on a broad selection of articles, I was under the mistaken belief that Wikipedia was "good enough."
