The document discusses the Library 2.0 and iMoodle communities on Ning. It finds that both communities have a confusing mix of social and professional interactions that makes it unclear how and where to engage. It also notes that the large size of Library 2.0 makes interesting discussions hard to find and that activity seems sparse and outdated. While the potential is there, the document concludes that the communities have become too large and unmanaged for meaningful collaboration.
