It's unclear how she'll be funding her new operation—I hear she'll be taking venture funding—or exactly what the circumstances of her exit are. I was told by a staffer within News Corp. that the announcement of Lessin's move brought one colleague to "tears," and that she might've been prompted by some internal conflict at the Journal vis-a-vis promotions.

On the other hand, her marriage to Facebook product wiz Sam Lessin was problematic—you know, ethically.

I've asked Lessin for comment via email, but really, it's 9 pm her time, so certainly not reasonable to expect anything back yet.
