I don't think I've noticed the apostrophe one, but it's going to get me when I do.
My daughter and I noticed a particularly annoying use of punctuation that seems to be sweeping America: the use of quotation marks to emphasize truth, when they really imply skepticism.
For instance, we saw some product labeled "genuine" whatever it was, with the word genuine in quotations! To us, that implied the stuff was fake, but apparently the vendors thought the opposite.
Wanna put in a DVD tho...
Something naughty...
Team America -or-
Top Secret -or-
Better Than Sex...
SPBLU is overdone around here lately :)
I would find that annoying too, not to mention confusing.
The apostrophe-s mistake happens with common nouns... for instance, instead of typing "the dogs" when they mean more than one dog, the person will type "the dog's"... which always makes me want to ask, "The dog's what?" since apostrophe-s is the possessive form...
