The stage of creating women-only and women-focused groups ( and buying into the diminutive labeling the original author hates ), is what happens after you have a bunch of really, really, really shitty interactions.
Thus, I think it is likely the author simply hasn't had the kind of really poor interactions & groping & whatnot, and she doesn't mention it in her post.
I am passionate about this because my significant other is a woman, and she's in tech. I know plenty of other women in technology. Most of them aren't deeply involved in "women-in-tech" and prefer a low-key evangelizing of the great women that have been in tech, combined with fleeing from companies that employ ... jerks ... who harass and ignore.
I was very happy that, in my startup under my leadership, we had a 50% male-female ratio. Subsequently, as CTO without much staff, that ratio has steadily decreased, and we are now down to 0% women in engineering. While that can be sampling error ( we don't have a 1000 member engineering staff ), it does give me pause.
The women technologists I know don't specifically slag the "women-in-tech" movement as the author did, I suspect because they do realize the magnitude of the problem is great enough that multiple points of pressure are required. Simply being great isn't enough, and the problem is getting worse not better - but there are likely other reasons.
