Facebook indexing the web – Facebook Like

The biggest announcement of this week – Facebook Like. As expected there are lot of privacy concerns raised about the like button. So now any web site could add the like button in their website. When a facebook user (logged in facebook in the computer) visits that web page, he will see the following

1. Like button

2. List of his friends who liked this page

3. Total number of visitors who liked this page.

With this mass input of data about each of the website pages, Facebook could rank the web pages based on its popularity an dbased on its visitors rating. With this information,  facebook could easily develop a search , which could pull out all relevant links ranked based on popularity. Facebook will not need any web crawlers, to fetch information about web. Did Mark Zuckerberg struck a gold pot?
