I am fairly skeptical about self promotion of statistical data a company has gathered as part of a glitzy, appallingly designed and presented whiz-bang add for their own product.
However, let's say it is true, this is no different to any other first gen product being replaced by a second gen product. What is displaced? Probably Blackboard given Moodle's overall relatively poor performance in the US. Or is that given Moodle's great performance and ... oh I dunno.... One read says Moodle is #1 around the world, but doesn't rate a mention in the US.... why is that? Or have I been given dummy information? Or is Canvas single-handedly saving Ruby?
