Its great to see a Linkedin KM discussion group Women in KM set up only for women! And by four of my favorite KM women at that - well done Karen, Nerida, Diana and Jeanne :-)
As they explain in the Group description, they have set it up to see if it would be beneficial for women who are in a field that is often male-dominated. And that it is a chance for women to explore, network, share ideas about KM among other women.
Interestingly, I have noted that online forums are male dominated but I tend to find at conferences, workshops and certainly my knowledge cafes there are more woman - often a 60:40 or even 70:30 ratio of women to men.
