In my line of work, I keep a close eye out for poor spelling and general grammatical errors. I know that nobody is perfect but poor spelling makes you look uneducated but near-perfect spelling makes you feel better about yourself. I snicker at misspelled signs, misspellings in advertisements and the general mess that is Facebook because a life without spellcheck is a sad life indeed.
Below are some excellent examples of misspelled words. Feel free to take a stab at the intended word for each in the comments.
