A problem with open source software is that you never know exactly how many installations are out there. Our site yaug.org is still in its beginning and the absolute number of users is not overwhelming. But you have to account for the fact that YAWL is not a software for the end-user but a tool for process automation.
The first question is, where do YAWL users come from? You may find an answer to that question here. It contains the distribution of visits to the site yaug.org in 2013. All graphics come from our Piwik statistics.
