Social Sites
It has become increasingly difficult to follow the development in the social software space. Blogs, wikis, social tagging, networking sites, etc. A consolidation will surely take place over the next years but for the time being, one has to maintain a variety of profiles on different sites. Here are some of mine:
Profile on Facebook
Profile on Xing
Public profile on LinkedIn
If we assume that Web 2.0 technology will become an important of enterprise information management, corporate IT departments will have to handle a variety of challenges.
