“Starting Up” in a Facebook World

I wanted to follow-up quickly on my post regarding my view that while social is inevitable and here to stay, Facebook’s continued success is not necessarily inevitable.  If investing or starting up companies under this thesis, the ideal situation would be a portfolio approach where you would bet both on apps riding the trend and bet on something disruptive aiming to create a new category or trend. Easier said than done from the entrepreneurial perspective where you need to be “all in,” but perhaps possible, and certainly possible from an investing perspective.  Not unlike “bubble” investing, where there can be a lot of money to be made riding the trend, even when your underlying view is that the thesis is ultimately not sustainable.
