The Big Doubt Over Facebook-WSJ

This was a really interesting article on some of the concerns that advertisers are having about Facebook, and the inability to track whether sales are coming directly from their advertising efforts.  I remember hearing similar concerns about search advertising earlier in its development and I think it is likely that Facebook will make it easier for advertisers to track consumers activities.  It still does highlight the potential pitfalls that can occur in monetizing the opportunity that Facebook has.  At an expected valuation of $100 billion, I’d much rather invest in Google than Facebook, where I might have a slower growth rate, but Google has a variety of businesses which I expect to be able to increase profitability over time as they scale up, and the valuation is much more reasonable.
