Q: What if a new, community-created
site competes with my existing,
old-rules Stack Exchange?
If your existing Stack Exchange site
already has developed a substantial
community, we’ll encourage people to
go there, rather than creating yet
another Stack Exchange on the same
topic. Once again, our goal is to make
the Internet a better place to get
expert answers to your questions.
Competing with existing sites that do
a great job of that is not in our
However, if your Stack Exchange site
does not have substantial traffic, we
reserve the right to create a new site
on the same topic.
My own thoughts & analysis:
Technically, "we [Stack Overflow] reserve the right" covers the case at hand.
But I would point out that moms4mom.com is, IMHO, a well-functioning community doing a great job and having sufficient traffic. I'm personally surprised the proposal for parenting.SE has made it all the way to beta. I was expecting it to be delayed – for a while, but not forever.
However, a counter-point could be that once moms4mom.com moved off the Stack Exchange platform (to OSQA), it no longer fell under the first specific condition above, being "If your existing Stack Exchange site already has developed..."
But I would point out that even on OSQA, moms4mom.com still "makes the Internet a better place."
I see no clear cut-and-dry answer, and I think both communities have genuine, authentic goals, so I think you're right in qualifying "conflict-of-interest" with kinda.
It's simply unfortunate that there are now two communities, but c'est la vie.
