I thought it was interesting that BEER redirects to this page.

https://en.wikipedia.org/wiki/BEER

I didn't realize that Wikipedia was case specific:

https://en.wikipedia.org/wiki/Beer

Vs.

https://en.wikipedia.org/wiki/BEER

It's not 100% case-insensitive: the first character cannot be lowercase, so https://en.wikipedia.org/wiki/a and https://en.wikipedia.org/wiki/A are the same article.
