Hi Paul,
I wouldn't fancy an hour of any online learning, especially Bloom's Taxonomy.
I have been using the free version, MyUdutu for some time and like the product for the range of templates it offers and ease of use. For me it is easier than content authoring tools like eXe or Xerte and certainly easier than learning Flash. On this same basis it is easier for tutors to pick up, which I am working on in my support role.
As we are in a period of uncertaintly as to which if any LMS we have next year, this enables content to be developed that will run on any platform (it also has a Facebook application) I haven't worried too much yet about the SCORM capability but have certainly easily added Udutu-created content to Moodle, Janison and Facebook.
