Around the time of the end of my swapping of floppies back in the day, it was getting frustrating as none of the "cool" swappers accepted anything but 0day, and most would be annoyed if you couldn't regularly supply -7 to -14 day releases so they had a week or two to spread things to their downstream contacts before it'd be too stale. In other words a lot of them depended to a large extent on internal leaks... I remember receiving the occasional C64 game that was not even finished by the time it was spread.
