I first heard about it when I was in college, because several of the professors and lecturers in the CS department all disappeared to it for a few days, and told us a bit about the talks they were giving there, etc.
One of the things that Red Hat's Community Architecture team focuses on is the intersection of The Open Source Way and educators and educational institutions, including the growth of the Teaching Open Source community. Mel leads these initiatives for our team, and she's attending SIGCSE this year, along with Fedora contributor and current Olin undergrad Sebastian.
The collaboration that happens within Teaching Open Source has led to a panel discussion entitled Learning Through Open Source Participation, which is the only session title on the SIGCSE schedule which contains the string "open source". The panel includes Mel, Heidi Ellis, Matt Jadud, and Greg Hislop.
I'm excited that Red Hat and Teaching Open Source are going to be present at SIGCSE, and I want to figure out how collectively we can work to raise the profile of both those organizations for SIGCSE 2012, which just so happens to be in Shadowman's hometown of Raleigh.
I'd also like to send a shout-out to Nick Parlante who certainly doesn't remember the fact that I was one of his students a decade ago, but who is a great teacher and who runs an annual Nifty Assignments session at SIGCSE.
