I know I have mentioned the MinnMoms site here--it's a new site run by the St. Paul Pioneer Press to highlight newspaper articles that address mom issues. More to the point, it has community boards where I (along with 13 other metro moms) are talking and posting about the stuff that we are interested in.
We are having quite a lively discussion about Sarah Palin here. We are helping each other commit to writing with writing prompts here, and a round robin story here.
The main page is here, and you can contact me privately through that site. I'm AKAMom over there, and I hope you might come join us.
