I think the main mistake that most teachers make at WizIQ is the expectation of available paying students. One of the only areas that I take exception to WizIQ is their marketing themselves (and us) as a Teacher ready platform with paying students. When, in fact, we are almost the opposite.
There is almost no way that I see any teacher being able to advertise solely on WizIQ for acquiring students. Unfortunately, it is possibly dangerous to conduct classes publicly as the found paid students will then be exposed to free or nearly so classes by the majority of teachers here. This dicotomy for a business person makes our portal untennable.
My efforts have been and will continue to be to build a unique group of classes and teachers offering edutainment types of activities. If we can create enough groundswell and interest we could look at monetizing our joint offerings as a "educational channel" thingy. We have had several false starts (see previous Edupunk offerings) but I continue to believe this is a viable model.
