My history class last semester, The Ancient World (expert authority), prohibited the use of Wikipedia (communal acquisition of knowledge) for our research papers. Our professor and TAs suggested that Wikipedia was unreliable and riddled with errors regarding topics such as Athenian Democracy, the life of Julius Caesar, and so forth. However, most students including myself, found Wikipedia far more useful for these topics than other sources, not because Wikipedia was necessarily right, but because its phrasing and presentation were much easier to understand and follow than, say, a 1958 journal study on Greek myths and their contribution to democratic ideals. Yes, we ultimately used primary sources and journal articles as evidence in our papers, but to attain a basic understanding of the topic at hand, the majority of us first searched "Athenian Democracy" or "Julius Caesar" on Wikipedia for a broad, well structured group of information. After reading the Wikipedia article to understand the basics (which the website is almost always accurate about-- it is the minor details which are more likely to contain errors), we found ourselves better prepared to tackle the more complex primary sources and journal articles. Therefore, although ultimately we did not source Wikipedia for claims in our paper (or even the sources found at the bottom of Wikipedia articles), we used the website as a valuable stepping stone in our research.
I find communal acquisition of knowledge more useful, especially in the field of graphic design, which is a hobby of mine. Many graphic designers believe that the only way to get good at making images or designing websites is to take classes (expert authority) and read textbooks. While I have taken classes and used textbooks, which proved very effective at teaching concepts, I find the near infinite free knowledge regarding graphic design concepts (found in the form of Youtube videos made by professionals and amateurs alike, none of their credentials checked before publishing) far more interesting and useful. People online tend to use language that is easier to understand than that of the professionals. Furthermore, online videos (which are free) are far easier to access than expensive textbooks or classes. Due to the sheer number of amateur graphic designers, almost every concept you could ever think of is covered in a Youtube video, while this may not be the case in a time-limited class or page-limited book.
