So this site is a bit of an interesting oddball. On the tin it says parenting, but if you open it up inside you find questions on parenting, but also questions from the perspective of cousins, children, aunts/uncles, siblings, grandparents, even Great Cousins. None of these have been closed as off-topic, and it appears the community is accepting of these questions. I know I have come here before to ask things about for instance my infant nephew, or how to handle things with my aging mother, but the parenting tag itself has turned me off from this.
Then I came to Meta and saw a question How do we boost participation?. Given the scope of the site per community votes has expanded beyond just parents, it seems like it wouldn't be unreasonable to consider a new name for the site, something that is a bit more inclusive to all members of the family. I would suggest
Family Dynamics or something like that.
That being said, I can see an immediate problem, essentially, "How is a question about this behavior different from a cousin's perspective vs a grandparents perspective?". While depending on the behavior, in a lot of instances, it's not. A cousin or a grandparent can both be concerned about their relative's grades, and the answer is probably the same, to that end, we probably should avoid things like "Cousin" or "Grandparent" tags, or make sure there pop-up descriptions are very clear they should only be used when the type of relationship changes the answer to the question.
I thought about posting this as an answer to "How do we boost participation" meta-question, but realized that changing the scope of the site would probably require it's own meta-question for consideration.
