I did enjoy reading the research!
I liked all the general recommendations to encourage women participation: enforce community values, elevate thoughtful discussion, signal agreement and affirmation, etc.... and this too "To make products and services more successful for women, the social values have to be clearly defined, and products and services must adapt to a rich emotional communication,"
There is already a lot that the OTN and MOSC does to encourage women participation. eg awarding points for helpful and correct answers does promote agreement and affirmation.
It's also rare not to have civility in the forums too.
The OTN and MOSC is mainly about technical, but to encourage rich emotional communication maybe it's time to highlight and promote the more non-technical forums, like the "watercooler".... I would think richer emotional communication wouldn't come from the dry technical solutions, but instead come from lively discussion of IT industry trends, or IT career tips, or government policy towards IT, etc.....
