People who constantly complain about people who use "literally" or "ironic" or apostrophes incorrectly bother me more than the offenders themselves. People blog about this a lot. Any time they hear someone say something like "my head literally exploded" they blog about it because it makes them feel smart. This makes me think they probably aren't that smart, because if they were, they wouldn't have to point it out like that.
A lot of people I know that didn't go to college like to point out incorrect uses of "literally" and "ironic." They like to say that Alanis Morrisette's song wasn't actually about irony. Rain on your wedding day, they say, is just bad luck. This did not occur to these people on their own, most of them heard it on talk radio during morning show drive time. Morning show hosts are exactly the sort of people that love to talk about this sort of thing. I like belittling morning show hosts because they are more successful than me. I like writing things on my blog about how dumb other people are because it makes me feel smart. Literally.
