No they won't.
The penny has dropped for me on that one this morning.
Google IS getting some simple, basic, very powerful user metrics via the browser........you don't need links any more, you need advertising and a great user experience.
Have a look at the "Is Panda all about Exit Rates" thread.
You can now start a website and rank in Google by just creating a great user experience and advertising in a local newspaper.
Once people go to their browsers Google discovers your site and collects the user metrics to find out if people like it. If they like it, Google knows it's a good site and works out which keywords to rank it for.
