Social networking is a topic that is very hot in the information technology press at the moment. What is social networking? Social networking refers to a category of computer software to help friends, co-workers, customers or other individuals to work more effectively together. The key technologies in this space are blogs, Wikis and RSS.
We haven't seen a "critical-mass" in the use of social networking applications - most likely due to the lack of a transformative business case. Although the basic technology has been around for quite some time (think electronic bulletin boards) the technology still needs to mature and be better integrated with other applications before it will really take off.
