This is a very important issue to address, and whilst Moodle enthusiasts can give personal testament to the "cost" (in time) of ownership of small, personally supported Moodle installation, and Moodle Partners can give costs for hosting, what published evidence do we have of total cost of ownership in larger implementations? Has anything been published from New Zealand project?
I know that you could ask the same of Blackboard/Web CT.
My gut feeling is that Moodle has a chance of gaining a foothold in schools but in universities, who have already been through (at least) one expensive procurement round, IT services and management will want some hard evidence before moving to any Open Source product. I think some of them will do pilot projects in Moodle, but it is hard for these to be taken seriously if they are seen as the province of enthusiasts. The passion that Moodle generates is a double -edged sword (I can feel one edge coming my way soon
On our CABWEb project, we are very pleased with the service offered by Mediatouch, our Moodle Partner, but when I try to imagine Moodle being implemented at my University, I can see that this would involve interfacing with a number of systems, staff training, political will, etc. All this on top of users who have a different set of expectations, and reduced goodwill compared with the pre-VLE environment.
Anyway, enough! I think these Top Ten Myths are a great idea and can have some "passion" in them , but we also need some "cooler" analyses of implementing Moodle. These should be critical in the positive sense of the word so that they can influence large businesses like Universities. Businesses are adopting Opensource and expect this to increase.
