What can be included in Wikipedia?

Wikipedia has only a few limitations on what topics it covers. Recipes and how-to articles are not included in the main namespace, but just about everything else is.

In which other encyclopedia do you find a list of sex positions, an article about nose picking or one about William Shatner's version of Lucy In The Sky With Diamonds? As long as an article is verifiable, informative and neutral, it has a pretty good chance of being acceptable (see What Wikipedia is not for some other common rules). We strive to collect the sum of human knowledge, some of which may be trivial, but nevertheless is part of our cultures and our histories. Wikipedia is not paper—‌we need not worry about space constraints.
