Parenting Is Different.
I may not be a high rep. user on Stack Exchange as a whole, but I have hung around for a little under 3 years now, most of that time on Stack Overflow. I like to lurk. When I can answer a question I do and when I can't find the answer, I ask, but mostly I lurk. I like to watch the community. After being on Stack Overflow for almost two years straight, modifying my brain for Parenting.SE was quite difficult. Let's face it, Parenting is different. Here's why I think so:
This isn't programming
The Stack Exchange model is great for questions that will have a concrete answer. There are a thousand ways to skin a cat and this model provides an exceptionally good tool for allowing everyone, all over the world to describe how they skin that cat. This is excellent for programming questions, excellent for database questions, excellent for questions where OP says "How do I do this with this:
[inserts stuff]". But parenting isn't programming (unless you are warped and think you are programming your children).
I would say the majority of questions that are asked here apply to a VERY specific situation. Some of these questions may even desire a similar outcome compared to other questions, but they aren't THE exact same question. Every human is unique, every situation is different. As a person coming from a community like Stack Overflow, that makes it very difficult wondering what I should flag as duplicates or flag as too localized. You can't have a blanket answer to cover everyone's needs.
Parenting is personal
These are our children. This isn't which IDE to use or which field to assign as a primary key. It's extremely difficult for parents to ask questions about their offspring, even on the internet. Parenting style is unique for all persons. It's also a subject we take extremely personal. Putting yourself out there for potential criticism of your style is a very real concern.
Asking is hard.
Providing enough detail to get a quality answer on Stack Overflow is simple:
"How do I convert this int to float in C♭"
Providing enough detail to get a quality answer on Parenting is not simple. You spend 3/4s of the time typing up the back story of why you are asking in the first place. Then you spend time after posting explaining missing details in the comments in response to everyone's request for further information. Asking here isn't fun (sorry). When I got to my fourth measly question I was grasping for straws.
What does this have to do with the question here?
I say all this because I don't think badges for question asking are going to help. And even if it does generate more content, what will the quality of that content be since people will just be going for badges rather than caring about what they post.
Side Note to user Joe - I had honestly not read through the most recent questions on the board that day or for the entire several days prior when I posted this. I stayed consecutive in my days simply because Parenting is always open in my browser. Sorry if I stole your thunder. I didn't mean to.
