Given that there is probably less attention for good ol' C projects these days, its probably educational for the masses of readers using interpreted languages to see a simple-ish project using a classic, compiled language.
In terms of binary size, memory usage, you probably can't beat a slim C project.
Difficulty of clean code/memory leaks/security aside, I think everyone should read or write some C every once in a while. Fix that software that doesn't work quite right on wine. Learn the linux kernel enough to fix a bug for hardware you own. Start some project like this. You might learn something, or strengthen some old mental muscles.
