Salesforce.com crashes Microsoft’s party

As the Microsoft Professional Developers Conference kicked off this morning in Los Angeles, bicycle riders outside the convention center distributed T-shirts and fliers promoting the Salesforce.com development platform, Force.com, according to the Seattle Post-Intelligencer Microsoft Blog. They also gave out donuts.
