I know how you all feel!
But - to throw a spanner in the works - I AM a happy user of Kaleidos! Ok, it is clunky in places but it has potential! I only just started working with in in September so straight into the newest release so I don't have "baggage" of what it used to be like etc.
I've decided to tackle it with the average to bellow average it savvy teachers and they can all see the potential!!! That's half the battle won. There are one or two - ironically the ones that went on the initial training - that will not touch it with bargepole but hey who cares!
I am lucky that developing the platform is my sole occupation so I can really give it a bash - watch this space next year!!! :D
