A survey released earlier this year by the University of Massachusetts Dartmouth says the percentage of companies that maintain blogs fell to 37% in 2011 from 50% in 2010, based on its survey of 500 fast-growing companies listed by Inc. magazine. Only 23% of Fortune 500 companies maintained a blog in 2011, flat from a year ago after rising for several years.

The trend in business is consistent with the broader loss of interest in blogging among all consumers. In late 2010, the Pew Research Center said blogging among adults ages 18 to 33 fell 2 percentage points in 2010 from 2008. “Blogging requires more investment. You need content regularly. And you need to think about the risk of blogging, accepting comments, liability issues, defamation,” says Nora Ganim Barnes, a professor at the university who wrote the report. One benefit of a blog: “It’s a tool and content you own.”
