That’s according to Ed Moran, a Deloitte consultant who just completed a study of more than 100 businesses with online communities. Not surprisingly, these sites failed to gain traction with customers. Thirty-five percent of the online communities studied have less than 100 members; less than 25% have more than 1,000 members – despite the fact that close to 60% of these businesses have spent over $1 million on their community projects. “A disturbingly high number of these sites fail,” Moran tells us.
