Wiki old-timers might remember that for the first month of Wikipedia, CamelCase was the only way to make hyperlinks. Back then, article titles had bizarre capitalization like "EartH" and "JapaN" and "ReLigion"! https://en.wikipedia.org/wiki/Wikipedia:CamelCase_and_Wikipedia
Here's how the Earth article looked in 2001 when Wikipedia was a month old, long before Wikipedians realized their fledgling online encyclopedia would be read (and edited!) by astronauts in space. Since then, the Earth article has been edited more than 14,000 times. It's a good day to read it!
