Queensland University of Technology is doing a survey on BPMN Usage. Anyone that uses BPMN to create process models for whatever purpose is welcome and encouraged to participate. These guy in general are doing a lot of good work for BPM, so I assume this is another worthwhile endeavor. Here is the info:

BPMN is gaining momentum in practitioner communities, up to a point that even those vendors who were initially reluctant to adopt it, can no longer completely ignore it. But what exactly are the factors that drive this acceptance? How satisfied are end users of BPMN with the notation? Do user experiences on BPMN match those by BPA tool vendors?

Jan Recker from the BPM Research Group at Queensland University of Technology is undertaking a worldwide survey on the use of BPMN by process modellers to shed light into this question. You can help Jan by completing the survey available here:
