This site treats a sequence of Camel Case Words as links.
It's kinda ugly!
It's a deliberate TechnologyAesthetic.
It also makes it easy to distinguish internal and external links. InternalLinksLookLikeThis and external links look like this. I deliberately write meta pages /withaleadingslash to distinguish them too.

It's incredibly syntactically cheap. It's super easy to learn and use.
I was pleased when I realized that the titles I wanted could be recognized with sufficient reliability despite my adding no additional markup whatsoever.
