We are courting msft employees to use Xobni again. At one point we had 16k msft employees using Xobni. Then they started beta testing Outlook 2010 internally and we weren't compatible, so we lost all but 1,000. Our seattle campaign was designed to let them all know we are now compatible with Outlook 2010. When MSFT buys a Xobni Enterprise license for their employees, they will easily pay back the cost of our advertising campaign :)

And despite some media theories, No we didn't do this to get MSFT to acquire us.
