In this thread: Wildly different definitions of what "widely used" means :) Did you know tools like uname [1] and cat [2] in GNU coreutils have essentially only had two contributors in the past decade?

I'm actually surprised by the amount of changes in 'cat'. One would assume a program like that is already 'done'.
"'cat -v' considered harmful" is an ongoing meme, but there's truth to it. http://harmful.cat-v.org/cat-v/
cat(1) concatenates files. Some software should be considered done.
