you know, the rise of spell check— and the coming of age of the first generation who were able to have had access to it during their childhood— has, I feel like, eliminated a shitton of common spelling errors that I used to see all the time; on the other hand, it’s just replaced that with endless misused homonyms. Especially ones that seem like they’d make logical sense, if one isn’t familiar with the etymology. I practically learned to read on horse books, so "free reign" looks eye-twitchingly wrong to me, but it looks reasonable to anyone whose default assumption isn’t "all human experience is about horses." Having someone "in your sites" looks right if you’re not thinking about sighting down a rifle or whatever.
and they bug me, because I’ve got prescriptivist instincts for all that I’ve tried to retrain them. but at the same time, I like how it shows that people haven’t changed, really. We’ve got different tools, but we’re not any smarter or better at learning how to write.
