A study by the Columbia Journalism Review shed some light on the issue of speed versus accuracy in online journalism and the secrets to profitability. Among unprofitable Web sites, 40% have their budgets controlled by print editors, nearly double the rate of profitable Web sites, of which only 21% have their budgets controlled by a print editor. The study also uncovered a resistance to copy editing for magazine Web sites; 11% of respondents said there was no copy editing for the online edition. One important consideration for magazine Web sites is the proliferation of social media and other Web 2.0 technologies. Nearly two-thirds of respondents (64%) have blogs on their Web sites, nearly three-quarters (73%) allow comments on posted online material. Three-quarters of magazines surveyed have a social media presence, and 47% of respondents describe their presence as "active."
