Yesterday my daughter watched me acting on my favorite SE site. She essentially said:
"Hey, that's cool. Can you recommend me a me a site there, where I could go to with my bunch of questions I have to ask?"
I admittedly had to deny her going here, since
She's going to get 12 that month (IIRC minimum age to legally participate at SE is 13, correct me if I'm wrong)
Her english skills aren't well developed enough, to participate in internationally aimed sites
I've done more research then later and found this beautiful site1, specifically designed for children's questions.
They're controlling more questions, and missing topics coming in from the interested children via e-mail.
I appreciate this model somehow, since (vs. a forum or SE), it's moderated by adults, and directed e-mail channels.
Though adults have their "blinders" strapped on, and may totally miss the question.
Also it keeps the kids safe from any totally off question attends of pedophile nature or such.
I've been infected now with the thought, if it would be possible to make up a site using the SE engine, that is specifically designed for
- childrens asking
- mainly children answering
- decent moderation by adults, merely keeping them safe
- probably language specific, since we can't expect children to be familiar with english to ask well formed questions
I know it's kind of opinion based, but could you imagine one goes well and have the right controls at hand, to set up such kind of sites with SE (in Area51)?
As @Oded and others confirmed the point, that it generally wouldn't be legal for children younger than 13, besides parent's explicit agreement, which apparently can't be managed properly,
I still think that +13 year aged teens till at least 16 need to be treated as children, and it would be a good idea to give them protection level moderated sites.
1)Sorry it's in german, and that's also part of the question somehow. But I'd suppose everyone else here might be intelligent enough to extrapolate this for their native languages.
