In my opinion, women should look to organising off-wiki. Women-only site Women.com was mentioned the other day on the Gender Gap Task Force page. Activism there could certainly fulfil a useful function.
Ultimately, I think there should be a separate site for the gender gap effort – combining a blog and a forum, much like Wikipediocracy – where women and men interested in narrowing the gender gap and documenting the existing problems can exchange views in an atmosphere undisturbed by men pretending to be women, men opposed to narrowing the gender gap, men arguing that it's not really proven that the gender gap is a problem, and so forth.
It could do wonders for the effort's signal-to-noise ratio, and could probably achieve exponentially more in terms of raising public awareness. As it is, discussions on-wiki get bogged down in arguments leading nowhere, and contributors' energies are dissipated.[1]
A well-publicised off-wiki site forming links to journalists and academics working in this field would be an ideal complement to this mailing list – which is useful for networking with researchers and Wikipedians, but creates little or no direct publicity. No journalist will comb through the voluminous discussions here. You need a place where you can summarise issues in a more easily digestible format.
Unrelated to this, some of you may be interested in an ongoing discussion of the Wikipedia gender gap happening on Hacker News / Y Combinator:
