one for the stay at home women. they can do extra visit teaching, activities twice a week. they can get together and blog about how hard life is, and how much better they are than working moms. they can share postpatrum drepression and anxiety meds. it'd be like a support group.
The other organization can be for people who just want to go to church and participate in RS without all the drama.
in my ward at least, they form their own little groups anyways. My wife doesnt like to be around the stay at home moms, they drag her down. i think this would make it easier for everyone. my wife wouldnt feel judged by mommy bloggers, and she wouldnt feel bad for obviously avoiding them whenever possible. i think that solves the divide problem.
