I am familiar with em thanks. I am a software developer and have done some web development in the past. Far be it from me to argue with professional typographers, but do you hear anyone saying "oh, the line lengths on paperbacks are far too long, I can't scan them"? Maybe it's just me but I'm a little tired of always having to cater the the very lowest common denominator. That narrow width seems almost ludicrously too narrow to me, it's like a childrens book. There has been research that suggests that most people don't finish articles, so it seems to me that maybe making columns so narrow is catering to the audience most likely to have such a short attention span that they probably won't finish your article anyway. Or maybe I'm just a moany old git :-)
