Followed a link from xkcd to get here. I can't claim to have read the whole series in 3 days (took more like a week) but at last I'm caught up. And I'm probably going to fail a class because I was reading QC instead of working on my final project, but these things happen, and I'm not going to blame Jeph for creating the most absurdly addictive webcomic ever. That's his job.
