Interesting question!
Does Elon Musk play on Chess.com?

I go much further. I publicly correct people when they use the wrong case when speaking or writing. We can't have people believe they can ignore, for example, the dative case and still expect to be taken seriously.
I prefer ablative case, so I can tell people where to go (if it were to become necessary).
I probably wouldn't have compiled such a list, if it weren't for this post and the series that follows.
