From Ubuntu
Papercuts are fast to fix, but annoying bugs. Our mission is to make Ubuntu shine by reducing them.
100 Papercuts focused on cleaning up these low priority bugs that developers were too otherwise busy to fix. The idea is that at least 100 papercut bugs would be fixed by each release.
Unfortunately, this initiative died a long time ago and there hasn't been much response to bringing it back.
I believe the revival of such an initiative (albeit maybe not limited to Ubuntu) would be beneficial for Linux on the desktop. While these bugs alone don't seem to matter, enough of them can kill a person.
