What about those who use both? My typical programs have the x.y format externally, with x indicating definitive stable releases, and y major changes (bugfixes and changes that don't alter features are not documented in external version numbers). At the same time I keep internal version numbers based on the date just for my own purpose (it's easier for me to change a few numbers in the program than to rename files).
