More than seven in ten (71%) of the nation's fastest-growing private companies now use Facebook and, among them, 85% say their efforts are proving successful, up 36 percentage points from the 54% that said so a year earlier, according to a study by the University of Massachusetts at Dartmouth's Center for Marketing Research

Inc. 500 companies are still ramping up their use of social channels. For example, 59% of those listed on the 2010 Inc. 500 ranking now use Twitter, up from the 52% who did so in 2009. Interestingly, that 2010 level is comparable to the 60% of Fortune 500 (F500) companies that reported using Twitter in 2010. However, F500 companies were later adopters: Only 35% used Twitter in 2009.

Blogging is an increasingly important tool for Inc. 500 companies: 50% have corporate-facing blogs, up from 45% a year earlier. Meanwhile, only 23% of 2010 F500 companies had a corporate-facing blog in 2010, nearly equal to the 22% recorded in 2009.
