Backlash among anti-Twitterers — reflected in scores of recent online comments to USATODAY.com — often center on unfamiliarity with the technology, its often narcissistic bent and the "random" use by many of its advocates, says Joseph Turow, a professor at the Annenberg School for Communication at the University of Pennsylvania.
"With the advent of every new medium — books, radio, TV, social networks — there is a built-in fear, social concern, that it will lead to lack of productivity and a general sense of dysfunction," he says. "This is one of the tropes of the arrival of any new media. Many consider Twitter a fad."
Twitter spokeswoman Jenna Sampson pointed to a recent blog post by Twitter co-founder Biz Stone. In it, he acknowledged the company has work to do in reaching out to those who are new to Twitter. "Defining a 'tweet' ... doesn't resonate with everyone," Stone wrote.
