That's they're choice.

I tend to agree. But even though I have a degree in English literature and creative writing, and have worked as a journalist and editor, I still have a few things that I routinely mess up. My thing is: sometimes a word gets double letters in certain forms. Run / running. Got / gotten. But this doesn’t always happen. Walk / walking. There are however some forms of some words where I can’t remember what is correct to do. I’ve gotten it wrong and been corrected. I’ve gotten it right and second guessed myself. Both of those have happened so many times that I can no longer keep it all straight.

So I have some compassion perhaps for people who screw up to/too because they’re caught in a false mneumonic dilemma. (There’s a good example of my trouble with double letters, by the way - I always type “dilemma”).

I swear in some cases it’s more of a pathology and less just mere ignorance.
