But sharing a quote you didn't write doesn't make you "better than anyone", it makes you a reader, not necessarily a thinker, and certainly not someone posturing as the sage who invented the quote in the first place.

Sharing quotes is like telling jokes (most of which weren't invented by the speaker). I don't think people will accept an argument against telling jokes.

On the topic of quotes, here's one of my favorites: "While programming, you can write fast programs, and you can write programs fast, but you can't write fast programs fast." Guess who said it?
