It was originally called "GScript" but that was too generic so the lead eventually came up with "Gosu" which let us keep our ".gs" extension.
I associate the word "Gosu" with the Korean/International StarCraft scene, where the word describes a very skilled player. I wonder the project lead was also thinking of that.
This is exactly what I was thinking.
Heh. Well, although the lead is probably several degrees removed from the StarCraft gaming world, the Korean meaning of the word did play a part. But, honestly, there are only so many 4 or 5 letter words that start with G and also have an S.
