A great response by VC Chris Dixon to Google’s ridiculous post on the company openness:

Google makes 99% of their revenue by selling text ads for things like plane tickets, dvd players and malpractice lawyers. Many of these ads are syndicated to non-Google properties. But the anchor that gives Google their best “inventory” is the main search engine at Google.com. And the secret sauce behind Google.com is the algorithm for ranking search results. If Google is really committed to openness, it is this algorithm that they need to open source.
