Typos are great to really wake up your readers. Especially when they are (sorta) grammatically correct.
The T-R typo can change 'That' (Standard English) to 'Thar' (Pirate English)right in the middle of a paragraph.
The C-V typo can change 'Cultures" (Collective) to 'Vultures' (Specific). That should get their eyes open.
Seriously, these examples actually came from commercial online news publications who should really know better.
It makes me appreciate the many fine editors and writers here on SOL.
Thanks for doing a great job.
