Setting aside your own personal favourite, and considering the state of agile, leadership, and the general job market, what course do you think should be released first?

What's the ideal length for a course?  What is, in your opinion, a great balance between value/depth of content and time to realized value?  What fits into your busy life?

Think about how you like to learn.  What should the maximum length of each complete topic be?

Do you think its important to have homework or exercises, even if nobody reviews/marks it?

When you buy learning products, and recalling the ones that have had the greatest impact on your life, is a community element, like forums or group coaching calls, important to you?  Does it affect your buying decision?

Real quick - beyond the four courses just mentioned, what is something you WISH someone could teach you/help you master, that NOBODY has properly addressed yet?

Anything else you think I should know about creating a great digital learning experience for you?
