The only thing I can think of is that all the SAH mom's got together more because there were more of them. My grandma tells stories to that effect. I seriously wouldn't survive without my internet friends, either, even now I sometimes feel a bit isolated - I'm a very social person. I have exactly 1 friend who is a SAHM. All the others work outside of the house, most of them full-time jobs 5 days a week. If I didn't have you and a couple others online and also my former pregnancy message board, I'd likely go a little bonkers.
