Re: Typographic Sins

This is a great poster and a great list. Through my Typography and Words and Images classes, I have learned a lot of these tricks and rules. Although sometimes I think you need to break them. Like the O's example below... it's just something small and simple but yet it breaks the rules and it does it well. Althought this may be silly, but I thought an apostrophe shows ownership to something or is a contraction to include the word "is", so I'm not sure why its O's and not Os. Am I wrong on this?
