Also, one thing Tereza mentioned, that "women who start businesses like to know what they’re doing", could be seen more as a problem to be addressed than a constraint to be worked around.
I believe that the status quo is not going to evolve much through anything that can be construed by naysayers as affirmative action. Rather, women with technical and/or entrepreneurial aspirations need to get over themselves, stop being so concerned about peer pressure or what anybody else will think, do what they love, and prove to others that it can be done. Laura Finton, founder of oneforty and a Tech Stars grad is a great example. She started her company as a single mom with young kids as a solo founder with no programming skills. Even though I'm not a Twitter person at all, I take my hat off to her. She's taking the time to tell her story to the Boston entrepreneurial community and leading by example.
I don't think it's that simple though. For a majority change, positive feedback is required along the lifecyle from knowing nothing to loving it and having entrepreneurial aspirations. I think the main problem is the mostly invisible peer pressure to do something else - not the peer pressure to not do something. This is why more female role models are needed and more tech-oriented schooling from a young age and more gender neutral literature, etc.
