Social media was one of the other areas of research in the study. The results there found that social media has seen very little use at all: Only 5% of companies reported using the technology, and even those saw no increase in proliferation for their organizations over the next 5 years. After considering this, I think the problem with adopting social media for internal learning is not just about changing hearts and minds that are camped in brick-and-mortar instructional design. I think part of the problem also has to do with a company's internal concerns: intellectual property protections, standards of performance, expectations of behavior in the medium, decorum, etc. I know from experience that intellectual property can be a very big one. This is especially true if we're talking about using social media not only as an internal link between employees, but also as a restricted communication line with external partners.
So in short, the hurdles for implementing social learning with organizations may not be simply a matter of culture, but also a matter of working out how the company can protect itself at or above current security levels while still enabling all that the technology has to offer.
