Considering there are other file formats that are used and occupy the same space as tar balls, the fact that tar balls are common for quite a bit of archiving should represent a win. Other formats (like zip, 7z, rar, etc) have come along and while they're in use and zips specifically are very common, tar balls are still used. Must speak something to them?
