Facebook Chief Executive Mark Zuckerberg will sell 41.4 million shares worth about $2.3 billion as part of an offering of 70 million Class A common shares of the social network.

Of course there is no reason for him to sit on the shares when he has a few swimming pools to buy, but it is a little odd that he should choose to do it now. Facebook shares are doing well and were expected to rise further as the company sorts out its mobile plans and starts making more cash.

However if Zuckerberg thought the shares were going to go up much more he would nuts to sell that many of them. After all he could always sell a small number so that he can buy a few Christmas prezzies.
