Some links to kick off your Tuesday:

* Web 2.0 is on the ropes, because Kleiner Perkins has stopped investing in such companies? Paul Kedrosky provides some skeptical balance.

* Does Citigroup shakeup mean Citigroup breakup?

* CalPERS is having some trouble selling some private equity assets on the secondary market. But the pension giant apparently has only itself to blame.

* Blackstone and Warburg Pincus are in talks to buy part of Sony Entertainment India.

* Charlie Gasparino’s book on Dick Grasso comes out today.

* I spent a lot of hours on Super Mario Brothers 2, blissfully unaware that I was playing a watered-down version.
