Two of Microsoft’s open licenses, the Microsoft Reciprocal License and the Microsoft Public License, have been certified by the OSI. This is a big deal because only with an OSI certification can you call your license an "open source" license.

This won’t be enough to satisfy the purists (since, to them, anything with Microsoft’s name on it is suspect) but it should be enough to get the utilitarians (like me) excited.
