Business2blog points out that Colin Powell's next gig is going to be as a part-time venture capitalist with Kleiner Perkins. Of course we Indians know Kleiner Perkins as the firm where Vinod Khosla works.
Coming back to Powell b2blog says:
Ultimately, Kleiner gets to trade off of Powell's prestige, while the 68-year-old ex-Secretary of State gets to share in Kleiner's profits without breaking too much of a sweat.
That's what is called a sinecure.
