lllllllll: witch grammar/spelling error[s] makes u the moist angry?

ColorStorm

• "it's" instead of "its" (weirdly, this is the one error that even intelligent people generally make)
• "your" instead of "you're" (fucking dumbasses)
• "one of the xxx yyy" where xxx is some superlative and yyy is some category, only yyy should be plural to anyone with even the slightest smidgen of logic in their head, yet people make it a singular. like "one of the greatest pie flavor is blueberry." I mean, how can a person be that fucking stupid? and yet, I see this all the time
• not putting an 's on a name when it's being used in the possessive sense, like "Jay decided to be a transvestite and put Hillary clothes on", i mean, there are many grammatical errors you can make, but how does this just not look immediately terribly, degenerately, derangedly wrong to someone?
• putting apostrophes on plurals, like "many flower's" or "the best one's", so fucking dumb to put an apostrophe just because in other cases words ending in s's happen to have apostrophes, with no regard or understanding for grammar whatsoever.
• Edit: here's a more recent one, everybody and their brother nowadays says "he and I" or "she and I" in the direct object, where obviously you need "he and me" or "she and me." I guess they just want to sound more sophisticated, but too bad they care about appearances more than reality.

You know what I think, I think people are really, really, shockingly illiterate nowadays. But auto-correct and spell-checkers cover up most of the errors, so it's only the grammatical errors (that they don't detect) that stand out.. if it weren't for those technologies, I wouldn't be so pissed off at specific grammatical errors as continuously shocked at how profoundly dumb the masses are, in everything they write. It's just a theory..
