Google, Facebook, Twitter: Not Enough Dollars to Go Around - Barrons.com

I’m glad to see someone else echoing my view.  Google seems the most vulnerable in my opinion as the only model the company has is an ad model.  At stunning figure seldom mentioned is that the Safari browser (Apple) dominates mobile mind share with something like 40%.  The article fails to even mention Apple as an advertising competitor.  Apple may have been slow get into the ad business, but they are there now and if they get good at it, watch out.  The market share is going to come out of someone’s hide.  Google has the most share so consequently the most hide to lose.

But as a whole, online ad spending is growing at a fairly predictable pace, and won’t be large enough anytime soon to justify all of the high-flying valuations on dot-com shares.
