Yahoo booting CEO Semel and then bringing in the founder Jerry Yang as his replacement is interesting but not inspiring. Founders of innovative companies are often whiz kid geeks who are great at developing technology but not so hot at managing the organization through a profitable strategy.  There are exceptions of course, like Mike Dell and Steve Jobs, and their exceptions are the sole reason I reserve hope for Yahoo and Yang.  Both of those guys ceded the top spot for a few years and came back.   Maybe Mr. Yang has developed a great set of skills while watching his predecessors Koogle and Semel - maybe not.  Experimenting with new ideas to improve on old problems was the theme that started “Jerry and David’s Guide to the World Wide Web”, but it’s a big risk to apply that strategy to a $38 billion company.
