Here is a useful intranet 2.0 survey, especially if enough people respond. It is being run by Toby Ward at President, Prescient Digital Media. I have taken it as they said you could even you do not have intranet tools. My blog is my personal knowledge management system but there is no firewall at Portals and KM. There is total transparent here. It just takes ten minutes and you will get the results. The more participation they get, the better the results and findings that they share all with you.
