I wouldn't say it's taken all the whimsy, but the community attempts to keep an "encyclopedic" tone.

In same cases it's turned into overcorrection from the good old Wikipedia days when, for example, the article about vampires was mostly not about actual vampire bats, or even about folklore vampires, but about a self-proclaimed "lifestyle" of people who supposedly consider themselves "real vampires". I remember those days! It was fun to see the rampant edit wars between serious and fringe editors.
