I remember crawling Freenode as a teenager with nobody to talk to about programming, and discovering ##C. At the time I had a basic idea of programming languages but was still pretty much a beginner. I started asking why my argument printer in C was printing a (null) and then unrelated stuff (envp :P), and some very helpful person in the channel patiently guided me to an initial understanding of pointers. This was about 16 years ago. I don't remember his name anymore but whoever you are, thanks for helping me out all that time ago.
