Her tweets continued, until finally Hoffman committed a major social media no-no and posted Silman's phone number on Twitter in case followers wanted "to tell Roberta Silman off."
Her tiff generated such a buzz that she finally issued an apology through her publicist.
"I feel this whole situation has been completely blown out of proportion. Of course I was dismayed by Roberta Silman's review which gave away the plot of the novel, and in the heat of the moment I responded strongly and I wish I hadn't.
"I'm sorry if I offended anyone. Reviewers are entitled to their opinions and that's the name of the game in publishing. I hope my readers understand that I didn't mean to hurt anyone and I'm truly sorry if I did," she wrote.
If you're heading out of town, should you think twice before tweeting it out to your followers?
One Arizona man thinks so.
Before leaving with his wife in June, Israel Hyman told his approximately 2,000 Twitter followers that they were "preparing to head out of town," that they had "another 10 hours of driving ahead" and later, that they "made it to Kansas City," CNET reported at the time.
But when they returned home, they found that someone had broken into their home and stolen video equipment he used for his video business – to the tune of a few thousand dollars.
"My wife thinks it could be a random thing, but I just have my suspicions," he told The Associated Press. "They didn't take any of our normal consumer electronics.
"The customers have never met me in person," Hyman said. "Twitter is a way for them to get to know me. I forgot that there's an inherent danger in putting yourself out there."
Det. Steven Berry of the Mesa Police Department, which is investigating the burglary, said: "You've got to be careful about what you put out there. You never know who's reading it."
In May, Today show weatherman Al Roker found himself in a blizzard of headlines when he snapped photos of potential jurors on his iPhone and -- in violation of court rules -- posted them to his Twitter page.
Newspapers had a ball, with the New York Post headlining a story with, "Oh, What a Twit!" But Roker promptly apologized to officials at Manhattan's Criminal Court. He called the mistake "inadvertent," but defended himself.
"Folks need to lighten up," he said in a later Twitter posting. "I'm not breaking laws . . . just trying to share the experience of jury duty. One that I think is important and everyone should take part in."
David Bookstaver, a spokesman for the state Office of Court Administration, echoed Roker's sentiment, while saying the picture taking was "ill advised."
"No harm was done," Bookstaver said, adding: "What's more important is this shows Al came to do his civic duty, and we're happy about that. It's a good example that nobody's exempt."
In March, the NBA came down hard on Mavericks Owner Mark Cuban for tweeting grievances against referees. The NBA hit him with a $25,000 find for publicly criticizing officials after the Denver Nuggets beat his team, the Dallas Mavericks.
Using Twitter, he complained that Denver's J.R. Smith was not called for taunting Antoine Wright after he missed a shot.
After he heard about the fine, he wrote, "can't say no one makes money from twitter now. the nba does."
