I almost quoted Stephen King on my blog, only a few sentences, I didn't because the quote wasn't entirely apt, I actually quoted Mother Theresa instead (I don't think she will sue me, I hope not!), but I didn't know there was anything wrong with that. He sometimes quotes songs and other authors in his books, I know because I usually read whatever book he's mentioned or quoted, or listen to whatever song he's brought up. Does he have to pay for that or ask permission? If anything, they should sorta pay him, not that he needs the money, but he's basically selling books for them since I'm sure I'm not the only reader who reads whatever he thinks is worth a mention.
