Well, I just found this thread and found it fun to read and interesting. I've read maybe fifteen pages, so I'm not sure if these have been mentioned, but here goes. I repeatedly read in posts the misuse of there for their, which drives me nuts. "There family went with them." This should've said their. I also see to used when it should say too. "It was to much money." This should've said too much. In both examples I've noticed that it isn't a typo and a case of their fingers typing too fast as the mistake is repeated throughout the post. I've chuckled at some of the phrases and realized that I say some of them without any thought as to the redundancy or slang. They are phrases that are common to my region or upbringing. I was brought up saying "picture show" for movie. "Mom, can we go to the picture show?" I don't know when that left my vocabulary as I now say movie.
