Interesting Wikipedia Articles
A list of Wikipedia articles I find especially interesting. Most of these are of obscure concepts that are surprisingly well documented given their limited relevance to the average person or otherwise weird.
Motif-Index of Folk-Literature - The Motif-Index of Folk-Literature is an attempt to categorize folklore by common motifs. As a nerd who likes categorization, that's an interesting concept, and it's especially so when considering that it was done in the 1930's when access to an exhaustive collection of folklore was much more difficult to come by than in the internet era. It's also interesting to try and break down something as inherently nebulous as folklore into a system of discrete categories. It's particularly notable as it's apparently used by folklorists in the present day, so apparently its creator did a good job.
Pangram - A phrase which contains every letter of the character in a given language's lithography. If you're familiar with the concept, it's likely in the context of fonts using the phrase "The quick brown fox jumps over the lazy dog" to show every letter of the font. You may also be familiar with the second most famous and in my opinion much cooler pangram "Sphinx of black quartz, judge my vow".
