This makes me SO MAD. I think because it just looks so stupid. All lower-case is not the way we write. It's not how our language works.
I've just renamed 6 files at work because the file-names were all lower-case even though there were TWO names in them. It looked like an eleven-year-old had named them. You can't just take one of the most important rules of the English language and decide never to apply it!
my cousin and i used to email. she never once used a single capital letter, like this. she would never even cap proper nouns like london. it wasn't like she sometimes forgot. she never used a capital letter in an email once. like, ever. the laziness and how stupid her writing looked really annoyed me. it would simply never occur to me to think 'oh, i'm going to dump a basic tenet of the language.'
Those file names that are all lower-case today just reminded me of this and how much I hate it when people just decide that capital letters are an optional extra.
I should have replied to my cousin in all-caps.
