There is another lesson here for feminists that PG does not fully articulate. In my experience, most women are similar to Jessica in that they do not fit naturally into an alphadog founder type role. The time-honored tradition for such women to be part of accomplishing great things, is to partner with an alphadog mate. Unfortunately, modern feminism is all about turning women into men, rather than guiding women to fit in as complements and partners to a strong man.
If Jessica was so important to YC, why don't more people realize it? Partly because I'm a writer, and writers always get disproportionate attention.
And also because she was not listed as involved when YC was first founded. I assume that Jessica was "The Fourth Man wants to remain anonymous for now"? https://web.archive.org/web/20050324095016/http://ycombinato...
