A lot of time is wasted in the comments explaining what spring is (because this is the timeframe Apple gave for Mac OS X Leopard's release). It would probably be helpful if future news posts defined "spring" to avoid this repetition.
Something like
In the United States, spring begins around March 20, and ends June 21. While this is different in other areas of the world, Apple operates primarily in the United States, so it is assumed their deadline for Mac OS X Leopard is June 21, 2007.
