The fact that there is still a #Linux IRC channel where you're permitted to ask questions that aren't strictly related to the Linux kernel itself is a miracle. It's also a miracle that they don't split the #C channel down into channels for the individual POSIX header files, since having a discussion about C programming would be (gasp!) too general. If you'd like to feel like shit because you're not obsessive-compulsive, IRC is definitely the place to go.
