Matt Simmons speaks at the April 2013 BBLISA meeting. From the description at http://www.standalone-sysadmin.com/bl...
"I got up in front of everyone and talked briefly about something that I've noticed - mainly about how I see our profession splintering, but that the splintered elements (such as network and storage administrators) aren't actually specialties of "system administrators", it's much more like the specialized administrators are specialist doctors, and system administrators are like general practitioners. The idea is still half baked, but that's the fun of a lightning talk, right? I didn't offer any answers, but I asked a lot of questions."
