Smart and dumb apostrophes When correcting a text for work today, I noticed that there were two different types of quotes and apostrophes used. Upon research, I learned that there are two different types: Smart quotes/apostrophes, which are curled (that’s), and dumb ones, which are straight (that's). The smart ones are hard to type; however, a couple of websites claimed that dumb quotes shouldn't be used in professional writing. I experimented with a few correction tools (entering 'thats' and see the correction) and found that dumb apostrophes were the default for all of them. Also, the display of smart quotes was weird on some programs (similar to this: ` ). So my questions are: Does anyone besides typographists care? Which one are you using? Did you know about this?See: http://smartquotesforsmartpeople.com/Example: "Don't be dumb" “You’re smart!”
