Look, I myself have instances of fumblefingers, and I make typos from time to time. I'm no stickler for Oxford English and I pepper my writing with colloquialisms. I use "ain't" and "gonna" and "hopefully" (which technically should be "one hopes"). Occasionally, I'll even say "anxious" when I should say "eager" (to be anxious is to be suffering from anxiety, not full of anticipation).
However, there seem to be two categories of people who don't know how to spell, to puncuate, or form actual sentences. 1) Hillbillies playing a banjo out on some Appalachian porch or 2) people under the age of 30.
Did the schools stop teaching English? Did it become an optional course in high school? Were the kids skipping class in favor of smoking dope? Is it too much texting? What's going on here?
By cracky (LOL), back in my day we graduated students prepared for college. Today many good institutions of higher education spend the first year bringing the students up to speed on skills they should have learned in high school.
