A famous journalist, and author of "The White Album" among others. Her "unique writing" is basically her ranting about how everybody is stupid and being incredibly pretentious and condescending towards everything. Although great with words, she is incredibly sarcastic and passive aggressive, and in a few sentences can make anybody or anything (such as Jim Morrison) look like shit.
Annoying "intellectual" who hates on everything:
"Oh, Joan Didion is Awesome!"
Cool chill actually educated person:
"your an annoying fuck. Go read Tom Wolfe"
