Personally I see them as a signal of the end of the bubble cycle. At the end of each bubble there have been these type of 2 weeks and you can make a killing courses. At the end of the .com crash we had 2 week Macromedia Flash courses where graduates where expected to make 90-100k walking out the door. In my experience these courses are a market signal and are temporal.
