I don't even have to be reading something to get annoyed by composition errors. Personally I would like to see every sports person and politician get dinged with a $$$ fine for using the words or phrases "um", "like", "you know", and all the other fillers people use while trying to figure out how to get an idea across. Thanks to Miss Liguzinski, my 5th grade teacher, for drumming good speaking patterns into our heads. Each day one of the students was put in charge of The Notebook, which recorded when a student used any of those fillers. I think the fine was something like 5 cents per infraction. When the kitty got pretty full, we'd have a classroom party with pizza or a movie and popcorn. By the end of 5th grade every one of us in the class was competent and fluent. To this day I can go off with an extemporaneous speech on any subject that interests me - much to the amusement or annoyance of Himself, depending on his mood!
Now the popular thing among young professionals and "the educated" seems to be starting out sentences with something like "And" or "So" even if all you're doing is replying to a question. It's not like you're using the word to string two sentences together! "Uptalk" too, that's another complaint of mine. Don't know what that is? Ending every danged sentence with a question mark? If you're making a declarative sentence then you don't end it in a question? GAH! As far as I can tell, it seems like you aren't sure about what you're stating and you need affirmation. To me it's a sign of weakness. OK, end of rant.
