Sorry pal, I can't help you with your Google query for "Erin O'Connor nude". Although she's a blogger, apparently she's not an exhibitionist - her old blog was named "Cant Watch".
The woman is a miracle. Somehow she has emerged from the English Lit. departments at Berkeley and the University of Michigan without succumbing to political correctness, and currently she's an associate professor at Penn. To top it off, she maintains a blog with Maurice Black called "Critical Mass".
I'm not sure where the name comes from, but it sure isn't about nuclear technology. Critical Mass is a succession of observations about life in academia, with its courses in things like "Rich White Males". Good grief.
If nothing else, keep checking in with her. Maybe someday she'll post some pictures...
