Jive Software recently did a survey about “collaboration software”, which includes social networking tools such as blogs and wikis, although it’s not clear if it also includes other collaboration tools such as ECM. I think the latter, since 63% of the respondents said that they have access to some type of collaboration software, 78% use it at least weekly, and half use it on a daily basis.
Social networking is definitely starting to make an impact in enterprises, however: 98% of the respondents know what a blog is, and 63% know what a wiki is. No question about whether those people can define any enterprise uses for blogs and wikis, however.
Link to the survey, Sandy?
Jive just sent me the results, not the survey itself (which I believe is closed). They said that they had conducted it using e-rewards.com.
