Maybe I am too theoretical, or too closely linked with the world of education, but it seems to me that there might be a confusion on that list about the kind of participation to encourage.
The kind of women I know are mostly teachers, or doctors, or work in research institutes. They are perfectly able to write about scientific subjects, and it seems to me that kind of participation would benefit the cause more than stating they need to see girly stuff to feel entitled to participate. They are not teenagers.
For instance an article about the pelagic ecosystem doesn't seem to me very gender-oriented.
And for personal preferences there are personal blogs...
