Google will buy Salesforce.com
Salesforce.com has much more then a technology... it has a sale force to sell to the enterprise market. No doubt to me... Google will sooner or later buy salesforce.com...... ask yourself... as a shareholder of both companies... would you agree? I would.
Appexchange with Google Apps makes absolute sense from the user perspective as well. We just did something similar but open source... http://www.applicationexchange.com
