In the ROS metrics document ( located at http://wiki.ros.org/Metrics) for 2013 the number of wiki pages (under the section ENGAGEMENT METRICS) is 22000+ . In 2012 it was 14000+ and about same in 2014 also.
What is the explanation of this blip? Did a lot of wiki pages came into existence in 2013 and then got removed in 2014?
Moreover, I’m unsure as to what does “wiki pages” actually represent? Was it the total number of wiki pages in existence? Or wiki pages edited/accessed?
