Eric Jackson makes a good case over at Forbesfor a Google fall from grace. He's sharp to point out Siri's encroachment on Google's search turf. And, as Jackson notes, Siri is only a Beta product! He covers the search/mobile issues well. Few people focus on another fundamental flaw with Google. Google's ecosystem stinks. It doesn't make money off of anything it does, outside of advertising. Google beat Yahoo! ( YHOO) because it set up a better advertising network. From a content standpoint, Yahoo! outclasses Google. Yahoo! digitized a concept old-time radio created: Give us 22 minutes and we'll give you the world. As CEO Marissa Mayer referenced on the company's recent conference call, Yahoo! must do a better job capitalizing on user behavior. Yahoo! is a "daily habit" for many -- rolling seamlessly from news to sports to finance to entertainment. Yahoo! needs to monetize that loyalty in more ways than one. That's one type of ecosystem -- the advertising meets content platform. Google also loses -- to Apple ( AAPL) and Amazon.com ( AMZN) -- when it attempts to tie together hardware, software and/or e-commerce. It's easy to make sense of what Apple and Amazon do and why they do it, as an investor and a consumer. Sure, Google's ad network is straightforward enough, but there's no coherent backup plan. What's the strategy with its disparate offerings? Where, other than via ad clicks, has Google set itself up to generate meaningful revenue?
