Right on. I'm all about learning, sharing knowledge, and having fun. Kudos to you and Ryan for having the balls to study in public. What I find interesting, and somewhat alarming, though, is that experienced web developers such as yourself seem to only now be learning the fundamental, bedrock principles of how the technology you use every day actually works. Maybe it's because high-level abstractions weren't widely available, or because the books I had on hand were Stevens' classics, but I learned network programming starting with socket(2), and to this day still ask what each of socket/bind/listen/accept do when I'm interviewing sysadmins, much less developers. It's remarkable to me that a whole breed of web developers today might not have any exposure to networking below the HTTP stack offered by their favorite programming language.
