This is a great article about the typos that we all use or at least see. I would have to say that #1 is by far the most prevelent, and a pet peave of mine when people do it (e.g., loose for lose). I am definitely, or should I say, was guilty of #2 for quite a while until my former boss made a bet with me about whether “it’s” should be used for possessive case. I was wrong…you use “its” with no apostrophe for possessive case, and only use the apostrophe for when you are trying to say “it is.” Anyways, there are 8 others, some I have done and probably still do on occasion, and some I have never done, but either way, it is an interesting read.
