Is there any possibility of the Mom4Moms community wanting to merge into parenting.stackexchange? Should we reach out to their community to discuss this or other possibilities?
I was one of the answerers on the Moms4Mom meta thread that talon8 mentioned.
At the time, I was pretty negative and critical - still smarting (vicariously) from the 1.0 -> 2.0 upheaval.
Subsequently, I came to a slightly more balanced view, and encouraged both parties to try and negotiate their way to not having competing sites. I don't know the ins and outs of the ensuing discussion, but I think the main sticking point was about ceding control of the community (more than the brand, content or advertising revenue).
Moms4Mom is a very gentle community compared to the often 'robust' tone on SE sites. I have no numbers, but I'd say that there are more ladies there (which can be both cause and effect of the gentleness). There are no subjective or wiki police, no rants, no comment-spats, no 'us and them'. The benevolent dictators are benevolent, because the site is their baby.
I would love for Moms4Mom to be on the SE platform, but if - as it appears - going it alone is the only way to protect the existing community, then that's sad, but so be it.
As @Juan says, I don't think they're going to want to merge. They're already using a different system for their meta.
In particular there is a lot of talk that they feel their community doesn't fit in the SE mold. Lots of what they consider 'on topic' is 'off topic' per this site's definition. There was also some objection to the whole notion of an "expert" that a lot of the SE sites are based around... that they don't want experts, they want real practitioners.
Basically, I think they were using the SE1.0 platform for something different than what parenting-SE is, so while there is some overlap, there's a LOT of non-overlap that doesn't make sense to merge and/or wouldn't be welcome.
And while I wish them well in wherever they take moms4mom, after lurking in their community for a while, I'm happy to not merge and see us build a new community... especially if we can do a better job about being more inclusive.
