For those of you who are not yet intimately familiar with the Open Specification Promise (OSP), this is a great video featuring my manager Jean Paoli discussing the ins and outs of the OSP (along with Amy Marasco and Tom Robertson). If you tune into Channel9 now, you will see Jean's mug front and center on the main page. If you check back later, you will want to go directly to the story here.
This story underscores the simplicity and beauty of the OSP. They discuss several specific scenarios and how the OSP promises allowance for developers in each case using clear and simple language.
