ActKM is a thriving KM community, heavily Pacific (Australia and Asia) but quite cosmopolitan. They run a list, an annual event, and some online resources. They have also just put up on their wiki a list of the surveys that have been done (or are being done) by members using the ActKM list, plus an interesting page on how to do the same. Plus, some of the surveys’ results are published.
All in all, something to look at if you’re into KM research. If you do, please consider posting the results too :-).
