The diagram above shows the range of questions being posed by you about your professional practice on the blogs. This is not a comprehensive selection of professional questions but the diagram illustrates the range of questions being posed and they all suggest further and deeper questions. What is also noteworthy is that some of the questions are in the same zone and these are identified by the same colours. This is one way of getting a SIG going ..... Some people have already started wikis as I discovered - this is another technological tool to support a SIG which you can use.
