Nothing says “I don’t give a crap” about readers than sloppy writing. Perhaps the writer for Yahoo! Makers wrote these instructions on an iPhone and didn’t bother with capital letters or punctuation to end a sentence:
I didn’t bother circling all the mistakes because I was afraid I’d run out of red ink. But you can see for yourself that she didn’t bother with the Shift key. She didn’t bother to end each sentence with a period, or spell cheesecloth correctly, or use the correct idiom if need be.
This is simply some of the sloppiest writing ever to appear on Yahoo!, and that saying a lot. If this were a third-grade writing assignment, she’d fail. She just phoned it in.
